降解VOCs的有机-无机光催化剂研究进展

RESEARCH PROGRESS OF ORGANIC-INORGANIC PHOTOCATALYSTS FOR DEGRADING VOCs

挥发性有机物(VOCs)带来了诸多危害,VOCs治理已成研究热点。光催化降解VOCs因其低成本、无二次污染、节能、高矿化率等优点被广泛研究。TiO 2、Bi 2WO 6、MOF和量子点等光催化剂已应用于VOCs的降解,并在此基础上构建一种新型有机-无机复合光催化剂。在构建有机-无机复合光催化剂的过程中,从复合催化剂的有机及无机组分、催化剂结构、光生电子调控等方面研究,以期为制备降解VOCs的新型有机-无机复合光催化剂提供新的研究思路。

Volatile organic compounds(VOCs)have brought obvious harms.VOCs treatment has become a hot research issue.Photocatalytic degradation of VOCs had been widely studied due to its advantages such as low cost,no secondary pollution,energy saving,and high mineralization rate.Studies on photocatalysts such as TiO 2,Bi 2WO 6,MOF and quantum dots had been applied to the degradation of VOCs.Based on this,a new type of organic-inorganic composite photocatalyst was constructed.In the process of constructing the organic-inorganic composite photocatalyst,organic and inorganic components of the composite catalyst,structure of the catalyst,and control of photo-generated electrons were reviewed to improve the photocatalytic activity of the catalyst,and to prepare an innovation path for organic-inorganic composite photodegradation catalyst for VOCs removal.
