通常，通过对光催化剂进行助催化剂改性，促进光生电子与空穴的有效分离，是提高光催化性能的有效途径。为了进一步提高光催化材料的光催化性能，迫切需要探索新型有效的助催化剂。本研究通过简单的浸渍途径将Cu（II）助催化剂成功负载在多种ag基化合物（如AgCl、Ag3PO4、AgBr、AgI、Ag2CO3和Ag2O）表面，并通过可见光照射下甲基橙光催化脱色和光催化苯酚溶液分解来评价Cu(II)/ ag基光催化剂的光催化活性。AgCl是典型的光敏银基化合物之一，通过优化Cu（II）助催化剂的用量，可以大大提高AgCl的光催化活性，所得Cu(II)/AgCl的最高光催化性能高于未改性AgCl的最高光催化性能。
Usually, cocatalyst modification of photocatalysts is an efficient approach to enhance the photocatalytic performance by promoting effective separation of photogenerated electrons and holes. It is highly required to explore new and effective cocatalysts to further enhance the photocatalytic performance of photocatalytic materials. In the present work, Cu(II) cocatalyst was successfully loaded on the surface of various Ag-based compounds (such as AgCl, Ag3PO4, AgBr, AgI, Ag2CO3, and Ag2O) by a simple impregnation route, and their photocatalytic activity of Cu(II)/Ag-based photocatalysts was evaluated by the photocatalytic decolorization of methyl orange and photocatalytic decomposition of phenol solution under visible-light illumination. As one of the typical photosensitive Ag-based compounds, the photocatalytic activity of AgCl could be greatly improved by optimizing the amount of Cu(II) cocatalyst, and the highest photocatalytic performance of the resulted Cu(II)/AgCl was higher than that of the unmodifi...
