摘要:

在高级氧化过程中,相比于羟基自由基、硫酸根自由基可无差别地氧化降解有机污染物的性质,活性氧粒子单线态氧可以有选择性地降解特定有机污染物,这一特点为处理复杂水体污染提供了另一种可行方案。分别从光促进、通过活性中间体以及在催化材料中构造特殊结构这3个角度,系统梳理了当前文献中报道的单线态氧生成的主要途径,并就各生成途径的优缺点做了比对。光促进途径涉及气-液-固三相反应,光能利用率需进一步提高,通过活性中间体生成单线态氧的途径往往不易准确把握活性中间体的含量。与这2种生成方式相比,通过在催化材料中构造特殊结构的单线态氧生成方式局限性低,在未来更具实际应用价值。

Abstract:

The specific organic pollutants could be selectively degraded by the singlet oxygen which is one of the reactive oxygen species during the operation of advanced oxidation processes,compared with the feature that the hydroxyl radical and sulfate radical could indiscriminately oxidize and degrade organic pollutants. This feature provides new and feasible solutions for the treatment of complex water pollution. In this paper,the main pathways of singlet oxygen generation reported in the current literature were systematically reviewed from the perspectives of light-promotion generation,generation through active intermediates and generation by constructing special structures in catalytic materials. Then the advantages and disadvantages of each generation pathway were compared. The light-promotion pathway involved gas-liquid-solid three phases reaction,the utilization efficiency of light needed to be further improved in future. The active intermediate pathway was not easy to accurately grasp the content of the active intermediate. Compared with the two generation methods,the generation method through special structures in catalytic materials was less limited and more valuable for practical applications in future.

Key words: non-radical active oxygen particle, singlet oxygen, wastewater treatment, degradation of organics
