Solar-driven water splitting to produce hydrogen may be an ideal solution for global energy and environment issues.Among the various photocatalytic systems,platinum has been widely used to co-catalyse the reduction of protons in water for hydrogen evolution.However,the undesirable hydrogen oxidation reaction can also be readily catalysed by metallic platinum,which limits the solar energy conversion efficiency in artificial photosynthesis.

Bi2MoO6/CdMoO4复合材料及其可见光催化活性研究

随着工业化发展带来的环境污染日益严重，越来越多的有毒有害物质危及人类的健康，而半导体光催化剂在解决环境污染方面有着巨大的应用前景。但是，许多单一光催化剂的活性总是不理想，比如：光能利用率低、量子效率低等。因此，获得具有高的可见光活性的光催化材料一直是研究者们关注的焦点。本文采用水热法制备了Bi2MoO6/CdMoO4 复合材料，通过XRD、SEM、TEM-EDS 对材料的结构进行了表征，采用DRS
