Abstract: Photocatalytic degradation of methyl orange over a kind of layered metaloxide was accomplished.K2La2Ti3O10,a layered perovskite-type compound with a 1.39 nm interlayer space,exhibited a low activity for methyl orange decomposition.The notable activity was obtained when K2La2Ti3O10 was acidified in 2 mol/L HNO3 solution.

Key words: layered K2La2Ti3O10, photocatalytic, acidification, methyl orange
