Abstract

Abstract : Purpose: This paper aims to investigate the photocatalytic activity of zinc doped MAO-TiO2 films under the optimum MAO treatment condition. Design/methodology/approach: The coating was prepared by micro arc oxidation, and the influence of doping on the properties of the coating was also investigated. Findings: The results show that the BET surface area is 78.25±0.03m 2 /g, total pore area is 76.32 ± 0.04m 2 /g, and the total pore volume is 0.2135 ± 0.0004cm 3 /g. The degradation ratio of the film electrode with Zn-doped in methyl orange solution is up to 94%. When the react circles is 10 times, the degradation ratio is up to more than 85% and remains steady. With the different reaction conditions, these kinetics of the reactions show some different formulas. Originality/value: A kinetic equation for photocatalytic activity is established.
