To enhance the performance of photocatalytic CO2 reduction, development suitable cocatalysts represents an effective strategy. Cocatalysts can interact with photocatalysts to improve light absorption capabilities and facilitate separation transfer photogenerated electrons holes. Moreover, they provide highly active surface sites that promote adsorption activation CO2, which leads acceleration reduction. Herein, WO3 is employed as a cocatalyst photoreduction g-C3N4-TiO2 heterojunction through facile scalable calcination method. In pure water, optimal WO3/g-C3N4-TiO2 (WCT) delivers high selectivity CO CH4 formation 48.31 µmol·g−1 77.18 in absence sacrificial reagent extra photosensitizer, roughly 13.9 45.7 times higher than (CT). strongly electronically, guiding across interface surface. The oxygen vacancies WO3, electron-enriched centers, not only charge form efficient channels but also capture suppress recombination. This strong interaction jointly reduction activity selectivity, offering feasible way design cocatalysts.
