2Construction of ZnIn_(2)S_(4)-CdIn_(2)S_(4) Microspheres for Efficient Photo-catalytic Reduction of CO_(2) with Visible Light显示文摘ZnIn_(2)S_(4) has emerged in water splitting and degradation of dyes due to its good stability and light absorption properties.However,there are still few reports of CO_(2) photoreduction.Herein,we successfully synthesized ZnIn_(2)S_(4) and obtained a series of ZnIn_(2)S_(4)-CdIn_(2)S_(4) heterostructured microspheres through the ion exchange method,and first used them in photocatalytic CO_(2) reduction in noble-metal-free systems.The activity results showed that these ZnIn_(2)S_(4)-CdIn_(2)S_(4) photocatalysts exhibit excellent catalytic activity under visible light,and the best CO yield is as high as 33.57μmol・h^(-1) with a selectivity of 91%.Furthermore,the stability and reusability of ZnIn_(2)S_(4)-CdIn_(2)S_(4) was firmly confirmed by diverse characterizations,including X-ray diffraction(XRD),scanning electron microscopy(SEM),transmission electron microscopy(TEM),X-ray photoelectron spectroscopy(XPS),energy-dispersive X-ray spectroscopy(EDX)and N2 adsorption measurements.Shitong Han Bifang Li Lijuan Huang Hailing Xi Zhengxin Ding Jinlin Long 2022Chinese Journal of Structural Chemistry2022,41,1:2

9A novel nomogram for prognosis stratification in salvage liver transplantation:a national-wide study with propensity score matching analysis in China显示文摘Background:Salvage liver transplantation(SLT)has been reported to be an efficient treatment option for patients with recurrent hepatocellular carcinoma(HCC)after liver resection(LR).However,for recipients who underwent liver transplantation(LT)due to recurrent HCC after LR in China,the selection criteria are not well established.Methods:In this study,data from the China Liver Transplant Registry(CLTR)of 4,244 LT performed from January 2015 to December 2019 were examined,including 3,498 primary liver transplantation(PLT)and 746 SLT recipients.Propensity score matching(PSM)analysis was used to minimize between-group imbalances.The overall survival(OS)and disease-free survival(DFS)between PLT and SLT in recipients fulfilling the Milan or Hangzhou criteria were compared based on the multivariate analysis,nomograms were plotted to further classify the SLT group into low-and high-risk groups.Results:In this study,the 1-,3-and 5-year OS and DFS of SLT recipients fulfilling Milan criteria(OS,P=0.01;DFS,P<0.001)or Hangzhou criteria(OS,P=0.03;DFS,P=0.003)were significantly reduced when compared to that of PLT group after PSM analysis.Independent risk factors,including preoperative transarterial chemoembolization(TACE),alpha fetoprotein(AFP)level,tumor maximum size and tumor total diameter were selected to draw a prognostic nomogram.The low-risk SLT recipients(1-year,95.34%;3-year,84.26%;5-year,77.20%)showed a comparable OS with PLT recipients fulfilling Hangzhou criteria (P=0.107). Conclusions: An optimal nomogram model for prognosis stratification and clinical decision guidance of SLT was established. The low-risk SLT recipients based on the nomograms showed comparable survival with those fulfilling Hangzhou criteria in PLT group.Kai Wang Fengqiang Gao Siyi Dong Jialu Ding Libin Dong Chuxiao Shao Zhoucheng Wang Xun Qiu Xuyong Wei Zhengxin Wang Jiayin Yang Qiang Xia Shusen Zheng Xiao Xu 2023Hepatobiliary Surgery and Nutrition2023,12,6:0
10Highly selective photocatalytic reduction of CO_(2) to CH_(4) on electron-rich Fe species cocatalyst under visible light irradiation显示文摘Efficient photocatalytic reduction of CO_(2) to high-calorific-value CH4,an ideal target product,is a blueprint for C_(1)industry relevance and carbon neutrality,but it also faces great challenges.Herein,we demonstrate unprecedented hybrid SiC photocatalysts modified by Fe-based cocatalyst,which are prepared via a facile impregnation-reduction method,featuring an optimized local electronic structure.It exhibits a superior photocatalytic carbon-based products yield of 30.0μmol g^(−1) h^(−1) and achieves a record CH_(4) selectivity of up to 94.3%,which highlights the effectiveness of electron-rich Fe cocatalyst for boosting photocatalytic performance and selectivity.Specifically,the synergistic effects of directional migration of photogenerated electrons and strongπ-back bonding on low-valence Fe effectively strengthen the adsorption and activation of reactants and intermediates in the CO_(2)→CH_(4) pathway.This study inspires an effective strategy for enhancing the multielectron reduction capacity of semiconductor photocatalysts with low-cost Fe instead of noble metals as cocatalysts.Qianying Lin Jiwu Zhao Pu Zhang Shuo Wang Ying Wang Zizhong Zhang Na Wen Zhengxin Ding Rusheng Yuan Xuxu Wang Jinlin Long 2024Carbon Energy2024,6,1:0
11S-scheme CoTiO_(3)/Cd_(9.51)Zn_(0.49)S_(10)heterostructures for visible-light driven photocatalytic CO_(2) reduction显示文摘CdZnS solid solutions with strong light absorption are promising materials for solar-driven COreduction;however,their relatively weak redox ability and intrinsic photo-corrosion limit their further development as a photocatalyst.The addition of a second photocatalyst with a suitable band structure to construct a S-scheme photocatalytic system can solve both problems simultaneously.Here,we report a S-scheme photocatalyst based on the heterostructure of CoTiO_(3)/CdZnS(abbreviated as CoTiO_(3)/Cd_(9.51)Zn_(0.49)S_(10))that enables the efficient photocatalytic reduction of CO.Detailed physicochemical characterization resolves the S-scheme charge transfer mechanism in this composite photocatalyst.With the well-designed structure of particles and desirable band offsets,this hybrid system offers visible light absorption in a broad spectral region,large surface area,strong redox ability,and fast carrier separation and transportation.Under visible-light illumination,the CoTiO_(3)/Cd Zn S hybrid system displays a CO formation rate of about 11 mmol hgcombined with a long-term operational stability.Besides,a high apparent quantum efficiency(AQE)of 7.27%is realized for the CO_(2)-to-CO reduction reaction by the optimized Co TiO/Cd Zn S hybrid under 420 nm monochromatic light irradiation.Bo Su Haowei Huang Zhengxin Ding Maarten B.J.Roeffaers Sibo Wang Jinlin Long 2022Journal of Materials Science & Technology2022,,29:0
12Selectively converting CO_(2) to HCOOH on Cu-alloys integrated in hematite-driven artificial photosynthetic cells显示文摘The integration of electrochemical CO_(2)reduction(CO_(2)RR) and photoelectrochemical water oxidation offers a sustainable access to valuable chemicals and fuels. Here, we develop a rapidly annealed hematite photoanode with a photocurrent density of 2.83 mA cm^(-2)at 1.7 VRHEto drive the full-reaction. We also present Cu-alloys electrocatalysis extended from CuInSnS4, which are superior in both activity and selectivity for CO_(2)RR. Specifically, the screened CuInSn achieves a CO_(2)to HCOOH Faradaic efficiency of 93% at a cell voltage of-2.0 V by assembling into artificial photosynthesis cell. The stability test of IT exhibits less than 3% degradation over 24 h. Furthermore, in-situ Raman spectroscopy reveals that both CO_(3)^(-2)and CO_(2)are involved in CO_(2)RR as reactants. The preferential affinity of C for H in the ^(*)HCO_(2)intermediate enables an improved HCOOH-selectivity, highlighting the role of multifunctional Cu in reducing the cell voltage and enhancing the photocurrent density.Jiwu Zhao Liang Huang Lan Xue Zhenjie Niu Zizhong Zhang Zhengxin Ding Rusheng Yuan Xu Lu Jinlin Long 2023Journal of Energy Chemistry2023,,4:0
13EFFICIENT CONTAMINANT REMOVAL FROM LIQUID DIGESTATE OF PIG MANURE BY CHEMICAL PRECIPITATION AND CO_(2) MINERALIZATION USING ALKALINE ASH显示文摘Chemical precipitation is a widely applied approach for a liquid fraction of digestate(LFD)of agricultural waste but its large-scale application requires low-cost and efficient precipitating agents and novel process design.This study evaluated novel approach for the efficient removal of contaminants from the LFD using fly ash-based chemical precipitation,followed by filtration and CO_(2) mineralization.The technical feasibility of this approach was evaluated using pH and electrical conductivity(EC),and removal efficiencies of total phosphorus(TP),chemical oxygen demand(COD)and heavy metals during the treatment.The fly ash used in this study showed a promising performance as a chemical precipitation agent for COD and TP removal from the treated LFD involving complex effects of precipitation and adsorption.CO_(2) bubbling after fly ash-based chemical precipitation provided further COD and TP removal by carbonation reactions between CO_(2) and the excessive alkaline minerals in fly ash.Although addition of fly ash to untreated LFD increased pH from 8.3 to 12.9 and EC from 7.01 to 13.7 mS·cm^(−1),CO_(2) bubbling helped neutralize the treated LFD and reduce the EC,and concentrations of toxic ions by carbonation reactions.The fly ash-based chemical precipitation and CO_(2) mineralization had>93%COD and>98%TP removal efficiencies,and resulted in an EC of<2 mS·cm^(−1) and a neutral pH in the treated LFD,as well as the high purity calcite product.Zhengxin FEI Zijie DING Xuan ZHENG Liang FENG Qingyao HE Shuiping YAN Long JI 2023Frontiers of Agricultural Science and Engineering2023,10,3:0
14Position-selected cocatalyst modification on a Z-scheme Cd_(0.5)Zn_(0.5)S/NiTiO_(3) photocatalyst for boosted H_(2) evolution显示文摘Photocatalytic water splitting by semiconductors is a promising technology to produce clean H_(2) fuel,but the efficiency is restrained seriously by the high overpotential of the H_(2)-evolution reaction together with the high recombination rate of photoinduced charges.To enhance H_(2) production,it is highly desirable yet challenging to explore an efficient reductive cocatalyst and place it precisely on the right sites of the photocatalyst surface to work the proton reduction reaction exclusively.Herein,the metalloid NixP cocatalyst is exactly positioned on the Z-scheme Cd_(0.5)Zn_(0.5)S/NiTiO_(3)(CZS/NTO)heterostructure through a facile photodeposition strategy,which renders the cocatalyst form solely at the electron-collecting locations.It is revealed that the directional transfer of photoexcited electrons from Cd_(0.5)Zn_(0.5)S to Ni_(x)P suppresses the quenching of charge carriers.Under visible light,the CZS/NTO hybrid loaded with the Ni_(x)P cocatalyst exhibits an optimal H_(2) yield rate of 1103μmol h^(-1)(i.e.,27.57 mmol h^(-1)g^(-1)),which is about twofold of pristine CZS/NTO and comparable to the counterpart deposited with the Pt cocatalyst.Besides,the high apparent quantum yield(AQY)of 56%is reached at 400 nm.Further,the mechanisms of the cocatalyst formation and the H2 generation reaction are discussed in detail.Bifang Li Wenyu Guo Xue Feng Lu Yidong Hou Zhengxin Ding Sibo Wang 2023Materials Reports(Energy)2023,3,4:0
