| 1 | Photoelectrocatalytic reduction of CO_2 to methanol over a photosystem Ⅱ-enhanced Cu foam/Si-nanowire system显示文摘A solar-light double illumination photoelectrocatalytic cell(SLDIPEC) was fabricated for autonomous CO_2 reduction and O_2 evolution with the aid of photosystem II(PS-II, an efficient light-driven water-oxidized enzyme from nature) and utilized in a photoanode solution. The proposed SLPEC system was composed of Cu foam as the photoanode and p-Si nanowires(Si-NW) as the photocathode. Under solar irradiation, it exhibited a super-photoelectrocatalytic performance for CO_2 conversion to methanol, with a high evolution rate(41.94 mmol/hr), owing to fast electron transfer from PS-II to Cu foam.Electrons were subsequently trapped by Si-NW through an external circuit via bias voltage(0.5 V), and a suitable conduction band potential of Si(-0.6 e V) allowed CO_2 to be easily reduced to CH_3 OH at the photocathode. The constructed Z-scheme between Cu foam and Si-NW can allow the SLDIPEC system to reduce CO_2(8.03 mmol/hr) in the absence of bias voltage. This approach makes full use of the energy band mismatch of the photoanode and photocathode to design a highly efficient device for solving environmental issues and producing clean energy. | Zichao Lian Donglai Pan Wenchao Wang Dieqing Zhang Guisheng Li Hexing Li | 2017 | Journal of Environmental Sciences2017，29，10： | 5 |

| 10 | Microwave-assisted synthesis of oxygen vacancy associated TiO_(2)for efficient photocatalytic nitrate reduction显示文摘The solar-driven photocatalytic technology has shown great potential in nitrate(NO_(3)^(-))pollutants reduction,however,it has been greatly hindered by the complex preparation and high cost of photocatalysts.Herein,a relatively low-cost photocatalyst,rutile and anatase mixed phase TiO_(2) was synthesized by a facile microwave-hydrothermal method.Meanwhile,oxygen vacancy is successfully generated,leading to an acidic surface for strong adsorption towards NO_(3)^(-),which further improved the reduction activity.Compared with the commercial P25,a higher NO_(3)^(-) conversion of ca.100%and nitrogen(N_(2)) selectivity of 87%were achieved under UV(365 nm)irradiation within 2 h.This research provides a promising strategy for designing efficient noble metal free photocatalyst in the NO_(3)^(-) reduction. | Qian Li Yunni Liu Zhe Wan Haiyan Cao Shao Zhang Yue Zhou Xingyu Ye Xiaoyan Liu Dieqing Zhang | 2022 | Chinese Chemical Letters2022，33，8： | 0 |
| 11 | Research Progress on Photocatalytic/Photoelectrocatalytic Oxidation of Nitrogen Oxides显示文摘The emission of nitrogen oxides(NO_(x))increases year by year,causing serious problems to our livelihoods.The photocatalytic oxidation of NO_(x)has attracted more attention recently because of its effi cient removal of NO_(x),especially for low concentra-tions of NO_(x).In this review,the mechanism of the photocatalytic oxidation of NO_(x)is described.Then,the recent progress on the development of photocatalysts is reviewed according to the categories of inorganic semiconductors,bismuth-based compounds,nitrogen carbide polymer,and metal organic frameworks(MOFs).In addition,the photoelectrocatalytic oxida-tion of NO_(x),a method involving the application of an external voltage on the photocatalytic system to further increase the removal effi ciency of NO_(x),and its progress are summarized.Finally,we outline the remaining challenges and provide our perspectives on the future directions for the photocatalytic oxidation of NO_(x). | Shuangjun Li Linglong Chen Zhong Ma Guisheng Li Dieqing Zhang | 2021 | Transactions of Tianjin University2021，27，4： | 0 |
| 12 | Highly selective and efficient photocatalytic NO removal:Charge carrier kinetics and interface molecular process显示文摘The widespread nitrogen oxides(NOx,mainly in NO)in the atmosphere have threatened human health and ecological environment.The dilute NO(ppb)is difficult to efficiently remove via the traditional process due to its characteristics of low concentration,wide range,large total amount,etc.Photocatalysis can utilize solar energy to purify NO pollutants under mild conditions,but its application is limited due to the low selectivity of nitrate and poor activity of NO removal.The underlying reason is that the interface mechanism of NO oxidation is not clearly understood,which leads to the inability to accurately regulate the NO oxidation process.Herein,the recent advances in the photocatalytic oxidation of NO are summarized.Firstly,the common strategies to effectively regulate carrier dynamics such as morphology control,facet engineering,defect engineering,plasma coupling,heterojunction and single-atom catalysts are discussed.Secondly,the progress of enhancing the adsorption and activation of reactants such as NO and O_(2) during NO oxidation is described in detail,and the corresponding NO oxidation mechanisms are enumerated.Finally,the challenges and prospects of photocatalytic NO oxidation are presented in term of nanotechnology for air pollution control.This review can shed light on the interface mechanism of NO oxidation and provide illuminating information on designing novel catalysts for efficient NOx control. | Huan Shang Hongbao Jia Pengpeng Li Hao Li Wenbin Zhang Shuangjun Li Qing Wang Shuning Xiao Ding Wang Guisheng Li Dieqing Zhang | 2024 | Nano Research2024，17，3： | 0 |
| 13 | Boosting the photocatalytic nitrogen reduction to ammonia through adsorption-plasmonic synergistic effects显示文摘Ammonia is one of the most essential chemicals in the modern society but its production still heavily relies on energy-consuming Haber-Bosch processes.The photocatalytic reduction of nitrogen with water for ammonia production has attracted much attention recently due to its synthesis under mild conditions at room temperature and atmospheric pressure using sunlight.Herein,we report a high-performance Au/MIL-100(Cr)photocatalyst,comprising MIL-100(Cr)and Au nanoparticles in photocatalytic nitrogen reduction to ammonia at ambient conditions under visible light irradiation.The optimized photocatalyst(i.e.,0.10Au/MIL-100(Cr))achieved the excellent ammonia production rate with 39.9μg g_(cat)^(-1) h^(-1) compared with pure MIL-100(Cr)(2.73μg gcat^(-1) h^(-1)),which was nearly 15 times that on pure MIL-100(Cr).The remarkable activity could be attributed to the adsorption-plasmonic synergistic effects in which the MIL-100(Cr)and Au are responsible to the strong trapping and adsorption of N2 molecules and photo-induced plasmonic hot electrons activating and decomposing the N2 molecules,respectively.This study might provide a new strategy for designing an efficient plasmonic photocatalyst to improve the photocatalytic performance of N2 fixation under visible light irradiation. | Yunni Liu Xingyu Ye Ruping Li Ying Tao Chi Zhang Zichao Lian Dieqing Zhang Guisheng Li | 2022 | Chinese Chemical Letters2022，33，12： | 0 |
| 14 | Microwave assisted synthesis of PQ-GDY@NH_(2)-UIO-66(Zr) for improved photocatalytic removal of NOx under visible light显示文摘Pyrazinoquinoxaline-based graphdiyne (PQ-GDY) contains a fixed number of sp-sp2hybridized carbon atoms and pyrazine-like sp2hybridized N atoms.In this paper,NH_(2)-UIO-66(Zr) on PQ-GDY substrate was successfully constructed with the help of microwaveassisted heating.PQ-GDY surface acts as a microwave antenna under microwave irradiation to rapidly absorb microwave energy and form hot spots (hot spot effect),which facilitates the formation of well-dispersed NH2-UIO-66(Zr) with good crystallinity.Transient absorption spectra show that high hole transport property of PQ-GDY can accelerate the migration of photogenerated holes from NH2-UIO-66(Zr) to PQ-GDY and greatly reduce the recombination rate of photogenerated electrons and holes due to the strong interaction between PQ-GDY and NH2-UIO-66(Zr).Under visible light (λ≥420 nm),PQ-GDY@NH_(2)-UIO-66(Zr) shows high photocatalytic stability and high NO_(x)removal rate up to 74%,which is 44% higher than that of primitive NH_(2)-UIO-66(Zr).At the same time,it inhibits the formation of toxic byproducts (NO2) and limits its concentration to a low level. | Qingyu Yang Shuangjun Li Rui Liang Lei Gao Shao Zhang Junfen Jia Yiran Liu Rundong Lyv Guisheng Li Shengxiong Xiao Dieqing Zhang | 2023 | Journal of Environmental Sciences2023，，12： | 0 |
