Abstract

The conversion of CO₂ into hydrocarbon fuels via the photocatalytic reaction route is considered a potential strategy to concurrently address serious energy crisis and greenhouse gas emission problems. Nevertheless, the generation of long-chain hydrocarbon products (C_n, n ≥ 2) from the visible-light-reactive photocatalytic CO₂ reduction has also been considering a contemporary challenge. Herein, we indicate that Ag nanoparticles (Ag NPs) loaded gC₃N₄/ZnO nanorods heterojunction (Ag-gC₃N₄/ZnO NRs abbreviation) has extended photoactive range and enhanced specific surface area. The combination of Ag NPs and gC₃N₄/ZnO NRs significantly enhances photocatalytic CO₂ reduction efficiency to form the acetone product. Detail, the acetone production efficiency of Ag-gC₃N₄/ZnO NRs is 8.4 and 7.5 times higher than pure ZnO NRs and gC₃N₄/ZnO NRs at the same condition, respectively. This study represents a potential approach toward higher-energy-value hydrocarbons production and greenhouse gas emission mitigation.
