Synergistic Enhancement of CO2 Photocatalytic Reduction Performance in Bi2-xWO6/Cu2O via Bismuth Vacancy Modification and p-n Heterojunction
This study demonstrates that constructing a Cu2O/Bi2−xWO6 p-n heterojunction with engineered bismuth vacancies synergistically enhances CO2 photoreduction performance and product selectivity by optimizing charge separation and lowering thermodynamic barriers for multi-electron reduction pathways.
