Can any one please help me out by giving some reason why ZnO is not a good photocatalyst as compared to TiO2.
It have a photo-corrosion in acidic media, and produced Zn(II).
Zinc from ZnO leaches out under acidic media.
Photocorrosion may be occur even in neutral solution.
Dear Dr. Nasima Khatun
About advantages and disadvantages of ZnO-based photocatalysts, please read the enclosed review papers published by my research group.
