摘要：

TiO2 nanotube arrays sensitized with AgInS2 nanoparticles (TiO2 NTs/AgInS2) were successfully fabricated by a two-step process of anodization followed by a successive ionic layer absorption and reaction (SILAR) method. The structural investigation by scanning electron microscopy and transmission electron microscopy indicated that the AgInS2 nanoparticles of diameters similar to 15 nm grew uniformly on the walls of the TiO2 nanotubes. The TiO2 NTs/AgInS2 exhibits excellent photocurrent and photoelectrocatalytic activities under visible light irradiation. The enhancement in the photoelectrochemical performance could be explained by the optoelectronic coupling between dispersed AgInS2 nanoparticles and TiO2 NTs. (C) 2015 Elsevier B.V.
