Accelerating carrier separation to boost the photocatalytic CO reduction performance of ternary heterojunction Ag-TiCT/ZnO catalysts.

Developing low-cost and efficient photocatalyst/co-catalyst systems that promote CO reduction remains a challenge. In this work, Ag-TiCT composites were made using a self-reduction technique, and unique Ag-TiCT/ZnO ternary heterojunction structure photocatalysts were created using an electrostatic self-assembly process. The photocatalyst's close-contact heterogeneous interface increases photogenerated carrier migration efficiency.
