摘要 用不同方法制备了CdS-Pt/TiO2复合光催化剂。催化剂通过X射线衍射、比表面和紫外-可见漫反射吸收进行了表征。以可见光光解水制氢为探针反应,考察了CdS-Pt/TiO2复合光催化剂的可见光活性。结果表明制备方法极大地影响CdS-Pt/TiO2复合光催化剂的活性。低结晶度的CdS与Pt/TiO2复合形成的CdS-Pt/TiO2复合光催化剂具有最高的可见光活性,其光解水的量子效率为6.95%。 CdS-Pt/TiO2 composite photocatalyst was prepared using a variety of methods.The photocatalysts were characterized by X-ray diffraction,BET,and UV-Vis absorption spectroscopic techniques.The photocatalytic activity of CdS-Pt/TiO2 composite under visible light(λ≥420nm) was evaluated by photocatalytic hydrogen evolution.It was found that the preparation method enormously influenced the activity of CdS-Pt/TiO2 composite.The CdS-Pt/TiO2 composite by low-crystalline CdS coupled with Pt/TiO2 had the highest activity and the apparent quantum yield amount was 6.95%.
