Abstract
AbstractA stable ZnTe@Cs3Sb2I9 catalyst with 3D/2D‐hollow‐composite structure is constructed for CO2 photocatalytic reduction via the in situ growth of Cs3Sb2I9 nanosheets on hollow ZnTe microspheres using lattice matching. The formed Tellurium‐Antimony (Te─Sb) bonds improved the poor contact at the heterojunction interface, effectively promoted charge separation, and successfully suppressed photocorrosion. The unique core‐shell structure not only strengthens light absorption but also improves CO2 adsorption capacity. Consequently, the S‐scheme heterojunction with the synergistic effect of chemical bonds and 3D/2D‐hollow‐composite structure significantly enhances photocatalytic performance. The ZnTe@Cs3Sb2I9 photocatalyst offers a CO selectivity of 90.5%, which is higher than that of pure ZnTe (22.9%) and Cs3Sb2I9 (56.9%). This structure holds great promise for practical applications in CO2 photocatalytic reduction.
