文摘

High-efficiency energy materials based on uniform Ag₂S and Sb₂S₃ nanoparticles co-sensitization on self-organized TiO₂ nanotube arrays (TiO₂ NTs/Ag₂S-Sb₂S₃) were prepared by a combination of two-step electrochemical anodization with facile successive ionic layer adsorption and reaction (SILAR) process. Uniform Ag₂S and Sb₂S₃ nanoparticles were distributed homogeneously on the surface of TiO₂ NTs. The influences of SILAR deposition cycles of Ag₂S and Sb₂S₃ played vital influences on the morphology, visible light response and photoelectrochemical performance of TiO₂ NTs/Ag₂S-Bi₂S₃. The co-sensitization largely enhanced the photoelectrocatalytic removal of Cr(VI) under solar light irradiation.
