| 1 | Bi/BiOCl Nanosheets Enriched with Oxygen Vacancies to Enhance Photocatalytic CO_(2)Reduction显示文摘BiOCl has been used in the photoreduction of CO_(2),but exhibits limited photocatalytic activity.In this study,Bi was in situ reduced and deposited on the surface of(001)-dominated BiOCl nanosheets by NaBH 4 to form Bi/BiOCl nanosheets enriched with oxygen vacancies.The as-prepared Bi/BiOCl nanosheets having low thickness(ca.10 nm)showed much higher concentration of oxygen vacancies compared to Bi/BiOCl nanoplates having high thickness(ca.100 nm).Subsequently,the photocatalytic activity of the Bi/BiOCl nanosheets enriched with oxygen vacancies for CO_(2)reduction was dramatically enhanced and much higher than that of BiOCl nanoplates,nanosheets,and Bi/BiOCl nanoplates.It showed that the improved photocatalytic activity in the reduction of CO_(2)can be attributed to the enhanced separation effi ciency of photogenerated electron–hole pairs of the oxygen vacancies on BiOCl nanosheets and Bi metals.This work demonstrated that the in situ reduction of non-noble metals on the surface of BiOCl nanosheets that are enriched with oxygen vacancies is favorable for increasing photocatalytic CO_(2)reduction. | Shuqi Wu Junbu Wang Qingchuan Li Zeai Huang Zhiqiang Rao Ying Zhou | 2021 | Transactions of Tianjin University2021，27，2： | 3 |
| 2 | Low temperature conversion of methane to syngas using lattice oxygen over NiO-MgO显示文摘The conversion of methane to syngas(H_(2) and CO)is an important route to produce high value-added products.Oxidize methane into syngas in the absence of gaseous oxidants is an economical route.In this work,NiO-MgO composite is successfully synthesized via an impregnation method.At 764 K,methane is directly converted to syngas on the NiO-MgO without gaseous oxidants.A synergistic effect of NiO and MgO was observed,in which NiO induced lattice oxygen of MgO mobility to oxidize methane and suppressed the formation of intermediates for side reaction.As a result,NiO-MgO exhibited enhancement of catalytic activity with the H2 production rate of 1241.0µmol g^(-1) min^(-1),which was 3.4 times higher than that of pure MgO.This work provides a direct guidance to understand of methane oxidation via lattice oxygen under low temperature(<773 K). | Junbu Wang Zeai Huang Ying Wang Jundao Wu Zhiqiang Rao Fang Wang Ying Zhou | 2022 | Chinese Chemical Letters2022，33，10： | 1 |

| 4 | Promotion of photocatalytic steam reforming of methane over Ag^0/Ag^+-SrTiO3显示文摘Methane(CH4)is not only used as a fuel but also as a promising clean energy source for hydrogen generation.The steam reforming of CH4(SRM)using photocatalysts can realize the production of syngas(CO+H2)with low energy consumption.In this work,Ag0/Ag+-loaded SrTi03 nanocomposites were successfully prepared through a photodeposition method.When the loading amount of Ag is 0.5 mol%,the atom ratio of Ag+to Ag0 was found to be 51:49.In this case,a synergistic effect of Ago and Ag+was observed,in which Ago was proposed to improve the adsorption of H2 O to produce hydroxyl radicals and enhance the utilization of light energy as well as the separation of charge carriers.Meanwhile,Ag0 was regarded as the reduction reaction site with the function of an electron trapping agent.In addition,Ag+adsorbed the CH4 molecules and acted as the oxidation reaction sites in the process of photocatalytic SRM to further promote electron-hole separation.As a result,0.5 mol%Ag-SrTi03 exhibited enhancement of photocatalytic activity for SRM with the highest CO production rate of 4.3μmol g-1 h-1,which is ca.5 times higher than that of pure SrTi03.This work provides a facile route to fabricate nanocomposite with cocatalyst featuring different functions in promoting photocatalytic activity for SRM. | Bingqing Tan Yinghao Ye Zeai Huang Liqun Ye Minzhi Ma Ying Zhou | 2020 | Chinese Chemical Letters2020，31，6： | 0 |
