简述了可见光光催化机理,指出该机理与紫外光光催化机理的不同之处在于其电荷传输与分离机制。介绍了改性二氧化钛可见光催化剂的研究进展,重点概述了ABO3型、ABO4型和铋系等新型含氧化合物光催化剂的近期研究进展。展望了含氧化合物可见光催化剂在环境净化领域的应用前景。
The visible-light-induced photocatalytic mechanism is briefly stated,which is almost the same as that of the ultraviolet-light-induced photocatalysis except for its charge transmission and separation mechanism. The latest modification technology progress and relevant opinions in titanium dioxide visible-light photocatalysts are introduced, with the emphasis on the development of ABO3, ABO4, and bismuth-containing complex oxide photocatalysts. Pros- pect on applications of oxygenate visible-light photocatalysts in the field of environmental remediation are presented.
