| 摘 要： | 银基半导体光催化剂作为近年来新的研究热点,在可见光下通常表现出较好的光催化活性,但光催化性能不稳定,反应过程中极易发生光腐蚀,导致光催化活性下降。此外,银基半导体通常比表面积小,无孔结构。本文综述了近年来银基半导体光催化剂的研究进展,介绍了如简单银化合物、异质结型复合体、银基固溶体及负载型银基半导体光催化剂的制备和应用。认为形成异质结、增大比表面积、丰富孔结构或通过形貌和晶面控制是解决上述银基半导体不足的有效方法,并结合银基半导体光催化剂的优点必将在光催化降解废水和制氢等领域有良好的发展。

| Abstract: | The silver-based semiconductor photo-catalysts have been considered as a new research hot spot in recent years. Silver-based photo-catalysts usually display high photo-catalytic activity under visible light irradiation, but poor stability due to the photo-corrosion, which causes the serious deactivation. In addition, the silver-based semiconductor is usually associated with small specific surface area and little pore structure. This review summarized and analyzed recent research progress in the fabrication and application of silver-based semiconductor photo-catalysts. Some typical silver-based photo-catalysts, such as simple silver compound semiconductor, silver-based hetero-junctions, silver-based solid solution and loaded silver-based semiconductor are introduced. The formation of hetero-junction, the increase of the specific surface area, the enrichment of pore structure, the regulation of morphology and the control of crystal facet were considered as the effective strategies to improve the catalytic performance of the silver-based semiconductor photo-catalysts. Combining with the advantages of silver-based semiconductor photo-catalysts will have a good prospect in photo-catalytic degradation of waste water and hydrogen production. |
