Hello, H2O2 is oxidant agent which caused of generating a hydroxyl radical, the last is regarded as a power which used to start a photo reaction.

But the photosensitizer mostly is color organic compound (i.e. dye), that needed to suitable level of energy to inject her electron to photosemiconductor in order to increase the efficiency of reaction.Please, find attachment file....
