光催化降解甲醛、VOC有毒有害气体研究进展

Research progress of photocatalytic degradation of formaldehyde and VOC

随着工业化不断发展,甲醛、VOC来源越来越广。其对环境和人体有诸多危害,治理成为焦点。光催化剂自20世纪70年代以来在环境治理方面的应用逐渐增多。光催化剂原材料来源广,反应条件温和,可为甲醛、VOC的治理提供技术支撑。光催化剂分为有机、无机及有机无机复合光催化剂。本文根据光催化剂不同分类进行梳理,总结光催化剂对甲醛、VOC治理现状的研究,展望光催化未来发展方向。

With the continuous development of industrialization,the sources of formaldehyde and VOC are more and more extensive.Because of many hazards to the environment and human body,the treatment of formaldehyde and VOC has become the focus.Since the 1970s,the application of photocatalysts in environmental governance has gradually increased.The photocatalyst has a wide source of raw materials and mild reaction conditions,which can provide technical support for the treatment of formaldehyde and VOC.Photocatalyst can be divided into organic,inorganic and organic inorganic composite photocatalyst.Based on the different classification of photocatalysts,this paper summarizes the current research situation of the treatment of formaldehyde and VOC by photocatalysts,and looks forward to the future development direction of photocatalysis.
