摘要
ZnO是一种重要的半导体光催化材料,但ZnO的禁带宽度较大、光生电子和空穴易复合等问题限制其在光催化降解染料领域的实际应用。通过贵金属Ag掺杂对ZnO进行改性。通过掺杂Ag调节ZnO能带结构、缺陷调控和协同效应,拓宽了光响应范围,抑制电子-空穴复合,使ZnO基光催化剂在光降解染料的催化活性显著提升。本文从Ag单掺杂、Ag与金属共掺杂、Ag与非金属共掺杂三个方面论述了Ag掺杂ZnO在光催化降解染料的研究进展。最后对未来Ag掺杂ZnO的研究方向进行了展望。
ZnO is an important semiconductor photocatalytic material.The wide bandgap of ZnO and the easy recombination of photo generated electrons and holes limit its practical application in the field of photocatalytic degradation of dyes.By doping Ag to regulate the band structure,defect control,and synergistic effect of ZnO,the photoresponse range is broadened,electron hole recombination is suppressed,and the catalytic activity of ZnO based photocatalysts in photocatalytic degradation of dyes is significantly improved.This article reviews the research progress of Ag-doped ZnO in the photocatalytic degradation of dyes from three aspects:Ag single doping,Ag-metal co-doping,and Ag-nonmetal co-doping.Finally,prospects for future research directions of Ag element-doped ZnO are discussed.
