1Metal nanoparticles induced photocatalysis显示文摘Photocatalysis induced by light absorption of metal nanoparticles(NPs) has emerged as a promising strategy for exploiting efficient visible-light-responsive composites for solar-energy conversion. In this review, we first introduce the light absorption of metal NPs and the mechanisms proposed in metal-induced photocatalysis(MIP). Then, its applications in water splitting, artificial photosynthesis and inert molecular activation are summarized. To address the challenge of low efficiency in this field, strategies in promoting catalytic activity are reviewed, and particular attention is paid to the particle-size effect of metal. Finally, the challenges and possible development directions of MIP are briefly discussed.Lequan Liu Xinnan Zhang Lufeng Yang Liteng Ren Defa Wang Jinhua Ye 2017National Science Review2017,4,5:7

9Revealing the illumination effect on the discharge products in high-performance Li-O_(2) batteries with heterostructured photocatalysts显示文摘Aprotic lithium–oxygen batteries(LOBs)have been recognized as novel energy storage devices for their outstanding specific energy density,while the large discharge/charge overpotential is a tough barrier to be overcome.Here,hetero-structured MoS_(2)/ZnIn_(2)S_(4) nanosheets have been prepared to capture visible light and the generated charge carriers are utilized for promoting both the oxygen reduction reaction and the oxygen evolution reaction.With the light illumination in the discharge process,the abundant photo-inspired electrons serve as the reaction sites to promote the reduction of O_(2) into LiO_(2) which is finally deposited as Li_(2)O_(2).On the contrary,the generated holes in the valence band can contribute to the low oxidization potential of Li_(2)O_(2) during the charge process.It delivers a low charge potential of 3.29 V,with an excellent resulting energy efficiency of 96.7%,much superior to that of 69.2%in the dark condition.It is noted that the involvement of photoelectrons has influenced the growth of Li_(2)O_(2) films on the MoS_(2)/ZnIn_(2)S_(4) nanosheets through the surface-adsorption pathway.The insights from the theoretical calculation confirm that the photoelectrons favor the absorption of LiO_(2) and the formation of the Li_(2)O_(2) film through the surface route.Therefore,this paper provides a deeper understanding of the mechanism of photoinspired charge carriers in LOBs and will enable further exploration of photo-involved energy storage systems.Hao Gong Tao Wang Kun Chang Peng Li Lequan Liu Xingyu Yu Bin Gao Hairong Xue Renzhi Ma Jianping He Jinhua Ye 2022Carbon Energy2022,4,6:0
10Design of BiOBr_(0.25)I_(0.75) for synergy photoreduction Cr(Ⅵ) and capture Cr(Ⅲ) over wide pH range显示文摘Conversion of hexavalent chromium(Cr(Ⅵ))to trivalent chromium(Cr(Ⅲ))is an effective way to reduce its environmental risk,especially via photoreduction process.However,over a wide range of pH values,it is still a great challenge to achieve a high removal rate,and the disposal of produced Cr(Ⅲ)should be concerned.In this work,we implemented a high removal rate at 98%for Cr(Ⅵ)and total chromium(Cr(T))over a wide pH range(4–10)through the synergistic effect of adsorption,photoreduction and immobilization on the surface of Bi OBr_(0.25)I_(0.75).The substitution of bromine by iodine reduced the adsorption energy of Cr(Ⅵ)on Bi OBr_(0.25)I_(0.75),promoting the adsorption of Cr(Ⅵ).Meanwhile,the introduced iodine upshifted the conduction band(CB),enhancing the reduction ability for Cr(Ⅵ)to Cr(Ⅲ).The negative surface of Bi OBr_(0.25)I_(0.75)can capture Cr(Ⅲ),achieving a high removal rate for Cr(T).The p H-independent feature for Cr(Ⅵ)and Cr(Ⅲ)removal make Bi OBr_(0.25)I_(0.75)a potential material for chromium-containing wastewater treatment.This work provides an effective strategy for removing chromium over a wide p H range.Lixia Jia Xin Tan Yanfang Li Yizhong Zhang Shiqian Cao Wei Zhou Xiang Huang Lequan Liu Tao Yu 2022Chinese Chemical Letters2022,33,6:0
11Partial oxidation of methane by photocatalysis显示文摘Methane chemistry is one of the“Holy Grails of catalysis”.It is highly desirable but challenge to transform methane into value-added chemicals,because of its high C-H bonding energy(435 kJ/mol),lack ofπbonding or unpaired electrons.Currently,commercial methane conversion is usually carried out in harsh conditions with enormous energy input.Photocatalytic partial oxidation of methane to liquid oxygenates(PPOMO)is a future-oriented technology towards realizing high efficiency and high selectivity under mild conditions.The selection of oxidant is crucial to the PPOMO performance.Hence,attentions are paid to the research progress of PPOMO with various oxidants(O_(2),H_(2)O,H_(2)O_(2)and other oxidants).Moreover,the activation of the selected oxidants is also highly emphasized.Meanwhile,we summarized the methane activation mechanisms focusing on the C-H bond that was broken mainly by·OH radical,O-specie or photogenerated hole(h+).Finally,the challenges and prospects in this subject are briefly discussed.Zhongshan Yang Qiqi Zhang Hui Song Xin Chen Jiwei Cui Yanhui Sun Lequan Liu Jinhua Ye 2024Chinese Chemical Letters2024,35,1:0
