Study on the Photocatalytic Degradation of Pesticides Using Ba CoO Composite Materials
In this paper,the photocatalytic degradation experiment was conducted with cobalt oxide(CoO)and barium-doped cobalt oxide(Ba-CoO)as the catalyst.The influence of pH,catalyst dosage,reaction time,temperature and initial concentration on the photocatalytic degradation effect was investigated.The results show that the acid condition is better,and the degradation rate of Ba-CoO catalyst can reach 54%at pH 5-6.Increasing the catalyst dosage to 0.02g gave the best degradation effect.The prolonged reaction time and the moderate increase in temperature can also improve the degradation rate.However,excessive or excessive reaction conditions can lead to a decrease in the degradation rate.Moreover,the doping of Ba significantly enhanced the photocatalytic activity of CoO.Therefore,Ba-CoO is a effective catalyst for photocatalytic degradation of pesticides.This study systematically investigated the effects of various influencing factors on photocatalytic degradation,which provided a theoretical basis for the development of efficient pesticide treatment techniques.
