摘要:

非均相光-Fenton技术是基于传统Fenton试剂法,通过引入光照和新型催化剂实现光催化氧化和Fenton反应的协同作用,促进活性自由基(如·OH)的生成和有机物高效降解的新型高级氧化技术。综述了非均相光-Fenton体系的技术特征、关键影响因素和氧化原理,详细阐述了铁物种与二氧化钛、石墨相氮化碳、氧化石墨烯/还原氧化石墨烯、钒酸铋以及三氧化钨不同类型半导体结合的非均相光-Fenton材料的光催化氧化原理和有机物降解机制。

Abstract:

Heterogeneous photo-Fenton system is based on the traditional Fenton reagent process with introduction of light irradiation and new type catalysts. It holds the synergistic effect between the photocatalysis and Fenton reactions to promote the production of strong oxidizing radical species as hydroxyl radicals(·OH) and achieve the degradation of refractory organics. The technological characteristics, key factors and oxidation mechanisms of heterogeneous photo-Fenton process were reviewed. Some typical heterogeneous photo-Fenton catalysts as iron species doped titanium dioxide, graphitic carbon nitride, graphene oxide/reduced graphene oxide, bismuth vanadate, and tungsten trioxide, respectively were elaborated with regard to the principal of photocatalytic and degradation mechanism of organics.

Key words: heterogeneous reaction system, photo-Fenton technology, photocatalyst, catalysis oxidation mechanism, water treatment
