| 英文摘要 | In this work, TiO_2 nanotube arrays(NTAs) sensitized with MoS_2 microspheres(MoS_2/TiO_2 nanocomposites) were prepared on a flat Ti substrate via two-step anodization and hydrothermal method sequentially.TiO_2 NTAs were composed of many orderly nanotubes, whose large specific surface area was favorable for light absorption and MoS_2 microsphere adhesion. The MoS_2 microsphere as a narrow band gap semiconductor extended the TiO_2 NTAs' absorption band edge to the visible region. The 2D structure of MoS_2 microspheres and the construction of heterojunction electronic field at the interface of MoS_2 microspheres and TiO_2 NTAs promoted the separation of photoinduced carriers. The MoS_2/TiO_2 nanocomposites could provide higher photoelectrochemical cathodic protection for 304 stainless steel(304 SS) under visible light than pristine TiO_2 NTAs. |
