Fundamental Study on Photocatalytic Film

Effect of Texturing by Micro-cutting

Abstract

This study aims to clarify the influence of surface topography on the photocatalytic reaction of TiO2 film surface. In this report, a textured TiO2 film was produced by conducting the anodic oxidation to the titanium plate with micro cutting grooves, and its wettabilty was evaluated. From a comparison, it was understood that the wettability of the above-mentioned TiO2 film is superior to that of polished and oxidized one. As a result, it is confirmed that the wettability of photocatalytic film can be improved by increasing both the surface roughness and actual surface area.
