With photocatalytic activity of commercially available photocatalysts, viz. ZnO, TiO〈sub〉2〈/sub〉 and SnO〈sub〉2〈/sub〉, a set of photocatalytic experiments was performed under similar conditions using crystal violet, basic blue and methyl red dyes in water. The comparison of photocatalytic activity of ZnO with the benchmark Degussa P-25 (TiO〈sub〉2〈/sub〉) catalyst as well as with AR grade TiO〈sub〉2〈/sub〉 and SnO〈sub〉2〈/sub〉 showed that despite low specific surface areas and larger grain sizes, ZnO displayed higher activity in the degradation of dyes.
