摘要：

The photoreduction behaviour of CO, on cadmium-loaded ZnS microcrystals and ZnS-CdS solid solution microcrystals was investigated. The photoreduction product on Cd-loaded ZnS was formate, and the highest quantum efficiency of production was 32.5%, which was twice as large as that obtained on bare ZnS microcrystals. However, solid solutions of ZnS-CdS microcrystals did not exhibit high activities for the photoreduction of CO,. With increasing mole fraction of CdS, the activities for formate production decreased, and the production of CO was observed for a CdS mole fraction of 0.5-0.67.
