有机农药光催化降解机理研究进展

应用光催化技术降解有机农药来减少农药对农业环境的污染是目前环境领域中的新兴研究课题。文章对光催化降解的机理以及不同种类农药（有机氯类农药、有机磷类农药、拟除虫菊酯类农药、氨基甲酸酯类农药、其他类农药）的光催化降解研究进展进行了总结。结果表明：在半导体纳米粒子和光催化体系组合作用下，有机农药均可得到有效的降解。本研究提出了光催化降解有机农药的应用前景，并对现行光催化技术的一些缺陷提出建议及展望，以期为有机农药光催化降解的深入研究提供参考。

Photocatalytic Degradation Mechanism of Organic Pesticides: Research Progress

The application of photocatalytic degradation of organic pesticides to reduce the pollution of agricultural environment is a new research subject in the field of environment at present. In this paper, the mechanism of photocatalytic degradation and the research progress of photocatalytic degradation of different kinds of pesticides (organochlorine pesticides, organophosphorus pesticides, pyrethroid pesticides, carbamate pesticides and other pesticides) were summarized. The results showed that: organic pesticides could be effectively degraded under the combination effect of semiconductor nanoparticles and photocatalytic system. In this study, the authors put forward the application prospect of photocatalytic degradation of organic pesticides, and gave some suggestions and prospects for the defects of photocatalytic technology, so as to provide reference for further research on photocatalytic degradation of organic pesticides.
