The introduction of Bi and S dual vacancies typically promote the adsorption and activation of CO₂ molecules, while simultaneously lowering the energy barrier for the hydrogenation of *C1 intermediates and subsequent C1-C1 coupling. A synergistic catalysis mechanism is proposed for the promising photoconversion of CO2. Sulfur vacancies enhance CO₂ adsorption and *CO generation, while bismuth vacancies make the adjacent S atoms more electronically accessible than the Bi atoms, resulting in highly reactive and promoting C-C coupling of *CO therein. This work elucidates the synergistic effects of cationic and anionic vacancies in CO₂ photoreduction, offering valuable insights for the development of advanced CO₂ photoreduction catalysts.
