摘要：Developing a & nbsp;photocatalyst & nbsp;for efficient reduction of carbon dioxide (CO2) is a long-term goal to address global climate change. In this work, a tube-like indium oxide@indium phosphide/cuprous oxide & nbsp;<bold>(</bold>In2O3@InP/Cu2O) photocatalyst was prepared by annealing-phosphidation of In-Materials of Institute Lavoisier-68 (In-MIL-68) followed by & nbsp;electrodeposition & nbsp;of Cu2O, which was used to reduce CO2 & nbsp;with water under & nbsp;light irradiation. Partial phosphidation of In2O3 & nbsp;endowed In2O3@InP/Cu2O with strong light-harvesting ability. The In2O3@InP & nbsp;heterojunction & nbsp;combined with & nbsp;in situ & nbsp;loaded Cu2O provided a dual Z-scheme heterojunction for efficient electrons-holes separation. Under the synergisms of each component, the optimized In2O3@InP60/Cu2O-1 exhibited strong adsorption of CO2 & nbsp;and excellent photocatalytic performance in CO2 & nbsp;reduction. The yields of CO and CH4 & nbsp;were 13.7 and 38.8 & nbsp;mu mol & nbsp;g(-1), respectively, after 5 & nbsp;h simulated light illumination, higher than the corresponding yields with In2O3 & nbsp;(CO: 7.2 & nbsp;mu mol & nbsp;g(-1), CH4: 13.2 & nbsp;mu mol & nbsp;g(-1)). This study may provide some insights into the design of specific ternary photocatalysts with dual Z-scheme charge transfer mode for CO2 & nbsp;reduction.& nbsp;(C) 2022 Elsevier Inc.
