Ni2+/TiO2纳米管的光催化活性
Photocatalytic Property of Ni2+/TiO2 Nanotubes
摘要
Abstract
Ni2 + /TiO2 nanotubes were prepared via a hydrothermal method using Ni2 + /TiO2 and NaOH as raw material. The structure and morphology of Ni2 + /Ti02 nanotubes were characterized by X-ray diffraction ( XRD) , Ultraviolet obvious spectrum ( UV-Vis) , and scanning electron microscope ( SEM). The photocatalytic reactivity was evaluated by the degradation of reactive RB at the room temperature. The results showed that Ni2 + /Na2Ti3O7 with extensive formation of nanotubes were obtained before treated at 550 ℃ , and with small dispersion in outer diameter (50-100 nm) and length of 12 μm. After treated at 550 ℃ , peaks of Na2Ti3O7 almost disappeared, and peaks of TiO2 had increased, the photocatalytic activity of the calcined nanotube samples greatly increased due to the formation of anatase phase.关键词
