【摘要】 用水热法分一步和两步分别制备了CdS光催化剂。对所制备的光催化剂进行载Pt实验,得到了其最佳载Pt量。用XRD、UV-Vis、XRF、SEM和TEM对光催化剂结构进行表征分析,并测试了其在可见光下的产氢量, 发现两步法制备的光催化剂产氢活性有明显提高。更多还原

【Abstract】 Cadmium sulfide photocatalyst was prepared by hydrothermal methods with one-step and two-step methods, respectively. Platinum was loaded on the surface of prepared photocatalysts and its optimal loading amount was examined. All the prepared photocatalysts were characterized by XRD,UV-Vis, XRF, SEM and TEM and their pohtocatalytic activity was evaluated by H2 evolution from water under visible light. It was found that the photocatalyst prepared by two-step showed markedly improved hydrogen production activity.更多还原
