Abstract

Photocatalysis technology enables the conversion of CO₂ into valuable carbon compounds. In this study, a stable CdS/Nb₂O₅ Z-scheme heterojunction was successfully constructed, which exhibited exceptional photocatalytic performance with the CdS loading of 15 %, achieving a maximum CH₄ and CO yield of 18.53 and 6.26 μmol g^-1 h^-1, respectively. The effective construction of a CdS/Nb₂O₅ Z-scheme heterojunction is the basis for the improved performance and stability of the photocatalytic system, which efficiently governs the directional segregation of photo-induced electrons and holes. This work provides a novel design and synthesis of stable CdS-containing Z-scheme heterojunction composite catalyst for highly photocatalytic CO₂ conversion, holding great significance for high-active catalyst development and clean energy production.
