| 2 | Kilogram-scale synthesis of carbon quantum dots for hydrogen evolution, sensing and bioimaging显示文摘The development of large-scale synthetic methods for high quality carbon quantum dots(CQDs) is fundamental to their applications.However,the macroscopic preparation and scale up synthetic of CQDs is still in its infancy.Here,we report a facile,green,kilogram-scale synthesis of high quality fluorescent CQDs derived from poplar leaves via a one-step hydrothermal method.Notably,the throughput of CQDs can reach a level up to as high as 1.4975 kg in one pot.The structure and properties of the as-prepared CQDs were assessed through TEM,XRD,XPS and various spectroscopic methods.The obtained high quality CQD s with a photoluminescent quantum yield of 10.64% showed remarkable stability in aqueous media,rich functional groups,high photostability,consistent photoluminescence within biological pH range and low cytotoxicity.On account of these good properties,we demonstrated the multifunctional application to electrocatalytic water splitting,Fe^3+ sensing and bioimaging.It showed remarkable electrocatalytic activity,Fe^3+ sensitivity and good biocompatibility.This study provides a green,facile,inexpensive and large-scale method for producing high quality CQDs,which provides application value for large-scale production of CQDs. | Weidong Li Yuan Liu Boyang Wang Haoqiang Song Zhongyi Liu Siyu Lu Bai Yang | 2019 | Chinese Chemical Letters2019，30，12： | 7 |
| 3 | High production-yield solid-state carbon dots with tunable photoluminescence for white/multi-color light-emitting diodes显示文摘Plastic waste is generally resistant to natural degradation and has become a major environmental pollution problem globally. The pollution of ecosystems seriously affects the health and survival of organisms,including humans. Much attention has been paid to finding suitable ways to convert plastic waste into high-value-added carbon materials. To this end, we report the high production yield(60%–85%) of carbon dots(CDs) for solid-state fluorescence(SSF) obtained by a one-step solvothermal method using waste expanded polystyrene as the precursor. The SSF mechanism of the CDs was also explored. Their emission wavelength, with a large full width at half maximum of 150–200 nm, exhibited tunable photoluminescence from white to yellow and orange. CDs powder was used to fabricate single-component white and multi-colour light-emitting diodes on UV chips. Overall, plastic waste was converted into tunable solid-state fluorescent CDs powder, which has promising applications in carbon-based lighting, by a simple solvothermal method that provides a viable method for recycling plastic waste. | Haoqiang Song Xuejian Liu Boyang Wang Zhiyong Tang Siyu Lu | 2019 | Science Bulletin2019，64，23： | 6 |
| 4 | Ethanol-derived white emissive carbon dots:The formation process investigation and multi-color/white LEDs preparation显示文摘Carbon dots(CDs)have attracted much attention due to their excellent photoelectric properties and potential applications.Although previous studies have shown that almost all organic molecules can be converted into CDs via chemical carbonization,the mechanism of the conversion process remains unclear.The hydrothermal/solvothermal method commonly used to prepare CDs is complicated and leads to the generation of many by-product CDs with similar structures.Considering that the purification of the synthesized by-products is difficult,the process of CDs formation cannot be readily analyzed and understood.Herein,we use ethanol as a carbon source to synthesize white-emitting CDs(W-CDs).Column chromatography separation shows that the synthesized W-CDs are composed of blue-,cyan-,and yellow-emitting CDs that fluoresce at wavelengths corresponding to the three emission centers of W-CDs.Although the samples have similar graphitic structure,they exhibit different surface states due to variations in the degree of oxidation and carbonization.Therefore,the red-shift in their emission peaks is attributed to an increased degree of carbonization in their polymer structure.Theoretical calculations verify the experimental results,and the prepared CDs are successfully used to develop multi-color and white light-emitting diodes(LEDs). | Boyang Wang Haoqiang Song Zhiyong Tang Bai Yang Siyu Lu | 2022 | Nano Research2022，15，2： | 5 |
| 5 | N-doped carbon dots coupled NiFe-LDH hybrids for robust electrocatalytic alkaline water and seawater oxidation显示文摘Electrolysis of seawater offers a highly promising and sustainable route to attain carbon-neutral hydrogen energy without demanding on high-purity water resource.However,it is severely limited by the undesirable chlorine oxidation reaction(ClOR)on the anode and the releasing toxic chlorine species,inducing anode corrosion and multiple pollutions to reduce the efficiency and sustainability of this technology.The effective way is to limit the overpotential of oxygen evolution reaction(OER)below 480 mV and thus suppress the ClOR.Herein,we demonstrate that nitrogen-doped carbon dots strongly coupled NiFe layered double hydroxide nanosheet arrays on Ni foam(N-CDs/NiFe-LDH/NF)can efficiently facilitate OER with an ultralow overpotential of 260 mV to deliver the geometric current density of 100 mA·cm^(−2)and a Tafel slope of as low as 43.4 mV·dec−1 in 1.0 M KOH.More importantly,the N-CDs/NiFe-LDH/NF electrode at 100 mA·cm^(−2)shows overpotentials of 285 and 273 mV,respectively,by utilizing 1.0 M KOH with 0.5 M NaCl and 1.0 M KOH with 1.0 M NaCl as the simulated seawater,well avoid triggering ClOR.Notably,despite the complex environment of real seawater,N-CDs/NiFe-LDH/NF still effectively promotes alkaline seawater(1.0 M KOH+seawater)electrolysis with a lifetime longer than 50 and 20 h,respectively,in 1.0 M KOH and alkaline seawater electrolytes.The investigation result reveals that M–N–C bonding generated between N-CDs and NiFe-LDH intrinsically optimizes the charge transfer efficiency,further promoting the OER kinetics. | Peng Ding Haoqiang Song Jiangwei Chang Siyu Lu | 2022 | Nano Research2022，15，8： | 3 |
| 6 | Electron-phonon coupling-assisted universal red luminescence of o-phenylenediamine-based carbon dots显示文摘Due to the complex core-shell structure and variety of surface functional groups,the photoluminescence(PL)mechanism of carbon dots(CDs)remain unclear.o-Phenylenediamine(oPD),as one of the most common precursors for preparing red emissive CDs,has been extensively studied.Interestingly,most of the red emission CDs based on oPD have similar PL emission characteristics.Herein,we prepared six different oPD-based CDs and found that they had almost the same PL emission and absorption spectra after purifiication.Structural and spectral characterization indicated that they had similar carbon core structures but diffferent surface polymer shells.Furthermore,single-molecule PL spectroscopy confirmed that the multi-modal emission of those CDs originated from the transitions of different vibrational energy levels of the same PL center in the carbon core.In addition,the phenomenon of'spectral splitting'of single-particle CDs was observed at low temperature,which confirmed these oPD-based CDs were unique materials with properties of both organic molecules and quantum dots.Finally,theoretical calculations revealed their potential polymerization mode and carbon core structure.Moreover,we proposed the PL mechanism of red-emitting CDs based on oPD precursors;that is,the carbon core regulates the PL emission,and the polymer shell regulates the PL intensity.Our work resolves the controversy on the PL mechanism of oPD-based red CDs.These findings provide a general guide for the mechanism exploration and structural analysis of other types of CDs. | Boyang Wang Zhihong Wei Laizhi Sui Jingkun Yu Baowei Zhang Xiaoyong Wang Shengnan Feng Haoqiang Song Xue Yong Yuxi Tian Bai Yang Siyu Lu | 2022 | Light(Science & Applications)2022，11，7： | 2 |
| 7 | Isolated Cu-Sn diatomic sites for enhanced electroreduction of CO_(2)to CO显示文摘Electrochemical CO_(2)reduction reaction(CO_(2)RR)to high-value product,CO,not only provides a key feedstock for the wellestablished Fischer-Tropsch process but also mitigates the greenhouse effect.However,it suffers from sluggish reaction kinetics,competitive hydrogen evolution reaction,and low selectivity.Herein,we report non-precious Cu-Sn diatomic sites anchored on nitrogen-doped porous carbon(CuSn/NPC)as an efficient catalyst for CO_(2)RR to CO.The catalyst exhibits outstanding selectivity with CO Faradaic efficiency(FE)up to 99.1%,much higher than those of individual Cu(66.2%)and Sn(51.3%)single-atom catalysts.Moreover,high stability is confirmed by consecutive 24 h electrolysis with high selectivity from CO_(2)to CO.Theoretical calculations reveal an obvious activation of CO_(2)with weakened C-O bonds and distorted CO_(2)configuration upon chemisorption on the CuSn/NPC catalyst.It is also suggested CuSn/NPC is more selective for the CO_(2)RR with dominant CO production during the electrolysis,rather than the competing hydrogen evolution reaction. | Wei Liu Haoqiang Li Pengfei Ou Jing Mao Lili Han Jun Song Jun Luo Huolin L.Xin | 2023 | Nano Research2023，16，7： | 1 |
| 8 | Dual sensitivity of spiropyran-functionalized carbon dots for full color conversions显示文摘Multicolor phosphors that respond rapidly to external stimuli are highly desirable for many applications, including lighting,optical displays and sensors. Herein, spiropyran(SP)-functionalized carbon dots(CDs) were synthesized with a broad-spectrum output that were responsive to both ultraviolet(UV)/visible light and pH. The SP-CDs possessed strong ester linkages between the UV-absorbing/blue-emitting CDs and blue-absorbing/red-emitting surface SP groups, allowing efficient F?rster resonance energy transfer(FRET) between the donor and acceptor. UV irradiation or acid addition cause the SP ring opening to merocyanine(MC) or protonated MCH+forms, respectively, together with the formation of sheet-like aggregates. These processes enhanced the red emissions by the SP groups and attenuated blue emissions from the CDs. These changes were fully reversible under visible light or basic conditions, respectively, allowing dynamic regulation of the fluorescence properties(emission colors from blue to red, photoluminescence(PL) intensity) under photoirradiation on the timescale of minutes. As proof-of concept, we demonstrate that the emission properties of the SP-CDs can be used to construct UV and pH sensing materials as well as light emitting diode(LED) with different colors. | Lin Ai Huimin Liu Rui Liu Haoqiang Song Ziqi Song Mingjun Nie Geoffrey I.N.Waterhouse Siyu Lu | 2022 | Science China Chemistry2022，65，11： | 0 |
| 9 | An engineered xCas12i with high activity,high specificity,and broad PAM range显示文摘Dear Editor,The clustered regularly interspaced short palindromic repeats-Cas(CRISPR-Cas)systems,including type II Cas9 and type V Cas12 systems,which serve in the adaptive immunity of prokaryotes against viruses,have been developed into genome-editing tools(Anzalone et al.,2020;Doudna,2020).Compared with type II systems,the type V systems including V-A to V-K showed more functional diversity(Yan et al.,2019).Amongst them,Cas12i has a relatively smaller size(1,033-1,093 aa),compared to SpCas9 and Cas12a,and has a 5'-TTN protospacer adjacent motif(PAM)preference(Yan et al.,2019). | Hainan Zhang Xiangfeng Kong Mingxing Xue Jing Hu Zikang Wang Yinghui Wei Haoqiang Wang Jingxing Zhou Weihong Zhang Mengqiu Xu Xiaowen Shen Fengcai Yin Zhiyuan Ai Guangyan Huang Junhui Xia Xueqiong Song Hengbin Li Yuan Yuan Jinhui Li Na Zhong Meiling Zhang Yingsi Zhou Hui Yang | 2023 | Protein & Cell2023，14，7： | 0 |
| 10 | Design strategies towards transition metal single atom catalysts for the oxygen reduction reaction-A review显示文摘The electrochemical oxygen reduction reaction(ORR)is pivotal in energy conversion via a 4e-ORR pathway and green hydrogen peroxide production via 2e-ORR pathway.Transition metal single atom catalysts(TM SACs)have attracted intense attention in recent years for ORR due to their high activity and near maximum metal atom utilization.The future development of TM SACs for ORR requires improved understanding of reaction pathways,since currently the true origin of activity remains contentious owing to the lack of qualitative/quantitative information about active sites.Knowledge-guided design is imperative for the optimization of TM SACs performance in terms of activity and selectivity.This review focuses on the latest progress in the design of TM SACs for ORR,placing particular attention on efforts to elucidate reaction mechanisms.Experimental evidence based on in-situ/operando characterization measurements,along with theoretical predictions,are summarized to deepen understanding of the structure-performance relationships at both atomic and molecular level.Finally,some perspectives are offered relating to the fundamental science needed for TM SACs to find practical application in energy storage and conversion devices.We hope this review will inspire the development of new synthetic routes towards high-performance ORR electrocatalysts for the energy sector. | Yaojia Cheng Hao Wang Haoqiang Song Kan Zhang Geoffrey I.N.Waterhouse Jiangwei Chang Zhiyong Tang Siyu Lu | 2023 | Nano Research Energy2023，2，4： | 0 |
| 11 | Engineering the synergistic effect of carbon dots-stabilized atomic and subnanometric ruthenium as highly efficient electrocatalysts for robust hydrogen evolution显示文摘Currently,the most efficient electrocatalyst for the hydrogen evolution reaction(HER)in water dissociation is Pt-based catalyst.Unfortunately,the high cost and less than perfect efficiency hinder wide-range industrial/technological applications.Here,by controlling the treatment temperature of tris(2,2-bipyridine)ruthenium dichloride hexahydrate,synthesis of compounds with novel ruthenium single/dual atoms(Ru S/DAs)mixed with Ru nanoclusters(Ru S/DAs+Ru NCs)and supported by carbon dots is demonstrated.These compounds are shown to be highly efficient and competitive catalysts for hydrogen evolution.Ru S/DAs+Ru NCs exhibit very high activity,with overpotentials of 15 and 40mV at a current density of 10mA/cm2 in 1.0mol/L KOH and 0.5mol/L H2SO4,respectively.Furthermore,the composites are found to possess outstanding stability and rapid HER kinetics.X ray absorption fine structure analysis,supported by density functional theory calculations,shows charge rearrangement in single-atomic Ru,and the Ru dual sites promote active hydrogen adsorption and recombination.Ru S/DAs and Ru NCs demonstrate high electroactivity due to the electroactive Ru 4d orbitals.The introduction of Ru NCs activates the carbon support,providing a high electronic conductivity to transfer electrons from Ru NCs to Ru S/DAs,and facilitates water dissociation for the HER process. | Yuan Liu Ning Chen Weidong Li Mingzi Sun Tong Wu Bolong Huang Xue Yong Qinghua Zhang Lin Gu Haoqiang Song Robert Bauer John S.Tse Shuang-Quan Zang Bai Yang Siyu Lu | 2022 | SmartMat2022，3，2： | 0 |
| 12 | Disulfide Crosslinking-Induced Aggregation:Towards Solid-State Fluorescent Carbon Dots with Vastly Different Emission Colors显示文摘Solid-state fluorescent multi-color carbon dots(SFM-CDs),prepared using the same precursor(s)without the need for dispersion in a solid matrix,are highly demanded for a wide range of applications.Herein,we report a microwave-assisted strategy for the prepara-tion of SFM-CDs with blue,yellow and red emissions within 5 min from the same precursors.The as-prepared B-CDs,Y-CDs,and R-CDs possessed bright fluorescence at 425 nm,550 nm,and 640 nm,and photoluminescence quantum yields(PLQYs)of 54.68%,17.93%,and 2.88%,respectively.The structure of SFM-CDs consisted of 5-oxo-3,5-dihydro-2H-thiazolo[3,2-a]pyridine-7-carboxylic acid(TPCA)immobilized on the surface of a carbon core,with the size of the carbon core and degree of disulfide crosslinking between CDs both increasing on going from the B-CDs to the R-CDs,as verified by mechanochromic experiments.The excellent solid-state fluorescence performance of the SFM-CDs allowed their utilization as the fluorescent converter layer in multi-color LEDs and white LEDs with a high color rendering index. | Rui Fu Haoqiang Song Xingjiang Liu Yongqiang Zhang Guanjun Xiao Bo Zou Geoffrey I.N.Waterhouse Siyu Lu | 2023 | Chinese Journal of Chemistry2023，41，9： | 0 |
