Synthesis and characterization of photocatalytic zinc oxide thin films
Photocatalytic zinc oxide (ZnO) thin films were synthesized and characterized on glass. First, a stable zinc peroxide (ZnO2) nano-particle colloid was produced. The 4 reagents were zinc acetate dihydrate, DI water, H2O2 and PEG 200. The colloid was spin coated and spray coated onto glass substrates,...
