Abstract

The rapid increase in atmospheric CO2 levels due to industrialization underscores the urgent need for innovative carbon valorization strategies. Photocatalytic CO2 reduction presents a sustainable solution; however, conventional systems suffer from inefficient charge separation and limited product applicability. Herein, a green and scalable tandem strategy is developed by integrating S-scheme photocatalysis with palladium-catalyzed carbonylation. A rationally designed CeO2/Bi2S3 heterojunction leverages its hierarchical structure, broad visible-light absorption, oxygen-vacancy-mediated charge dynamics, and the S-scheme charge transfer mechanism to achieve highly efficient photocatalytic CO2-to-CO conversion…
