Highlights: • Cu{sub 0.91}In{sub 0.09}S microspheres were deposited on TiO{sub 2} NTs by a photodeposition method. • The average diameter of Cu{sub 0.91}In{sub 0.09}S microspheres is 600 nm. • The TiO{sub 2} NTs/CIS shows high photocurrents and visible photocatalytic activity. - Abstract: TiO{sub 2} nanotube arrays sensitized with Cu{sub 0.91}In{sub 0.09}S microspheres (TiO{sub 2} NTs/CIS) were successfully fabricated by a two-step process of anodization and followed by an in situ photodeposition method. The structural investigation by scanning electron microscopy and transmission electron microscopy indicated that the Cu{sub 0.91}In{sub 0.09}S microspheres with average diameter of 600 nm grew on the surface of the TiO{sub 2} nanotubes. The TiO{sub 2} NTs/CIS exhibited more excellent photoelectrochemical properties and photocatalytic activities than those of TiO{sub 2} NTs under visible light irradiation, and the corresponding electron transformation was proposed in detail.
