摘要：Nanostructured films of rhombohedral Ni3S2 were hydrothermally synthesized on Ni and TiO2 nanotube layer, as substrates. A possible mechanism is proposed to explain the formation of rhombohedral Ni3S2 nanostructures. The results of UV-vis spectrophotometric studies indicate that optical absorption spectrum of Ni3S2/TiO2 nanotube composites could be extended to the visible region. As-synthesized Ni3S2/TiO2 nanotube composite films on Ni substrate had better (by about 40%) hydrogen production performance under the visible light irradiation, in comparison with the Ni anode modified by TiO2 nanotubes.
