摘　　要：多相光催化处理废水是解决环境污染和水资源短缺紧迫问题的绿色可行且有工业化应用前景的技术之一。Co掺杂的催化剂能有效抑制光催化反应中被激发的光生电子-空穴对的复合,其高效的电荷转移能力和足够的活性位点,能有效地降解水中苯酚,且Co具有磁性有利于其从水中分离并重复利用。研究Co基催化剂在光催化降解苯酚方面的进展,将为后续酚类污染物的高效光催化去除技术的选择提供参考。Multiphase photocatalytic treatment of wastewater is one of the green feasible and industrialized application technologies to solve the urgent problems of environmental pollution and water shortage.The Co-doped catalyst can effectively inhibit the recombination of the excited photogenerated electron-hole pair in the photocatalytic reaction,and its efficient charge transfer ability and sufficient active sites can effectively degrade phenol in water,and the magnetic property of Co is conducive to its separation and reuse from water.The progress of Co-based catalysts in photocatalytic degradation of phenol will provide some reference for the selection of efficient photocatalytic removal technologies for phenolic pollutants in the future.
