Research Progress in Photoelectrocatalytic Degradation of Pesticides
Pesticide is a kind of environmental pollutant with high hazards and difficult to degrade,and pesticide residues cause serious damage to the ecological environment and jeopardize human health.Photoelectrocatalysis has become one of the most promising advanced oxidation technologies for degrading pesticide residues due to its advantages of safety,environmental protection,strong oxidizing ability and easy operation.The basic principle of photoelectrocatalytic degradation of pesticides,commonly used electrode materials and preparation methods are reported in this study,with emphasis on summarizing the latest applications of photoelectrocatalytic degradation of pesticides.And the effects of light source,pH and other influencing factors on pesticide degradation are evaluated,which provide the basis for short-term practical applications.However,there are fewer research studies on actual pesticide wastewater degradation,and the degradation of actual pesticide wastewater in the future should be emphasized in addition to the electrode material improvement.
