Abstract

Photocatalytic reactions are an environmentally friendly proposal to degradation of toxic compounds in polluted water. In this work, copper catalysts supported on TiO₂-P25 for catalytic photodegradation of pesticides in water were synthetized. Three different type of pesticides highly toxic; dichlorvos, cypermethrin and carbofuran, were characterized using Raman spectroscopy. CuO photocatalysts supported on TiO₂-P25 were characterized at each step of the preparation, after drying (120 °C, 4 h) and after calcination (300 °C, 4 h) using UV-vis diffuse reflectance and Raman spectroscopies. Results shows that the synthesized catalysts can be a suitable alternative to photodegradation of pesticides in water.
