Cooperative Catalytic Effect Analysis of Visible Light Response Nano-ZnO and TiO₂

Abstract:

Nano-ZnO, nano-TiO₂ and their mixed catalyst respectively degrade methyl orange solution with concentration 10mg/L in sunlight. When the dosing quantity is 1g/L during 8h degradation, the degradation effect is better and the degradation rates of three catalysts can all reach more than 93% with prolonging of degradation time, and the degradation effect of mixed catalyst is best and its degradation rate reaches more than 99%. Moreover the effect of TiO₂ content in the mixed catalyst on catalytic degradation isn’t distinct.
