Boosting selective photocatalytic CO2 reduction to CO over Dual-core@shell structured Bi2O3/Bi2WO6@g-C3N4 catalysts with strong interaction interface

The binary co-catalysts supported dual-core@shell structural photocatalysts (Bi2O3/Bi2WO6@g-C3N4) with strengthened Z-scheme heterojunctions improves the light absorption efficiency and the separation efficiency of photoinduced electron-hole pairs. The electrons enriched co-catalysts with strong interaction among each component transfer light-separated e- to the catalytic surface for reactants activation. The adsorption capacity of intermediates by catalysts could be adjusted by the ratio of core and shell, which results in the enhancing selective photocatalytic CO2 reduction into CO.
