TiO{sub 2} nanotube arrays sensitized with Sb{sub 2}S{sub 3} microcrystalline were successfully fabricated by a two-step process of photodeposition method followed by annealing treatment. The structural investigation by X-ray diffraction, scanning electron microscopy and transmission electron microscopy indicated that the Sb{sub 2}S{sub 3} microparticles grew uniformly on the walls of TiO{sub 2} nanotubes. The amorphous Sb{sub 2}S{sub 3} microspheres could be transformed into octahedral microcrystals after annealing treatment. The Sb{sub 2}S{sub 3} modification of the TiO{sub 2} nanotube arrays resulted in an increase in visible light adsorption and photocatalytic activities toward degradation of methyl orange (MO) and rhodamine B (RhB) dyes under visible light irradiation. - Highlights: • TiO{sub 2} nanotube arrays sensitized with Sb{sub 2}S{sub 3} microcrystalline were prepared. • The amorphous Sb{sub 2}S{sub 3} microspheres transformed into octahedral microcrystals after the annealing treatment. • The TiO{sub 2} NTs/Sb{sub 2}S{sub 3} exhibits excellent visible light photocatalytic activities.
