Synthesis and characteristics of natural zeolite supported Fe3+-TiO2 photocatalysts

► Natural zeolite supported Fe3+-TiO2 photocatalysts were synthesized. ► Zeolite restrained the growth of crystallite sizes. ► The iron ions could diffuse into TiO2 lattice to the form Fe-O-Ti bond. ► Photocatalytic activity of the samples could be enhanced as iron ions were doped.
