Short summary
With photocatalytic activity of commercially available photocatalysts, viz. ZnO, TiO2 and SnO2, 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 (TiO2) catalyst as well as with AR grade TiO2 and SnO2 showed that despite low specific surface areas and larger grain sizes, ZnO displayed higher activity in the degradation of dyes.
