摘要：

A 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 & horbar;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.
