Photocatalytic Degradation of Isoproturon Pesticide on C, N and S Doped TiO2

... car- bonyl group and bands at 1130, 1040 cm -1 are corre- sponding to nitrite and hyponitrite groups present in TCNS5 and they are absent in TCNS0 which shows suc- cessful doping of nitrogen into ... doping of C, N and S elements in titania brings visible light absorption photocatalytic activity of titania. It can be seen from the DRS spectra that C, N, and S...
