In this research, the photocatalyst of titanate layer compounds, K_2Ti_4O_9 and H_2Ti_4O_9, were prepared and characterized to compare their photodecomposition of methylene blue dye. Silver loading photocatalysts were prepared by reduction under blacklight irradiation. The photodecomposition activities of methylene blue dye were in the order of K_2Ti_4O_9/Ag>K_2Ti_4O_9>H_2Ti_4O_9/Ag>>H_2Ti_4O_9.
