具有可见光响应的C、N共掺杂TiO2纳米管光催化剂的制备
Fabrication of C,N-Codoped TiO2 Nanotube Photocatalysts with Visible Light Response
摘要
Abstract
To enhance the absorption in the visible region for TiO2,C and/or N doping of TiO2 nanotube was carried out by a novel method--plasma electrolysis.The doping was achieved with active C and N produced from the plasma electrolysis of HCONH2 NaNO2.or(NH2)2CO.The results of XPS revealed that C and N were successfully doped into the lattice of TiO2.UV-Vis diffuse reflectance spectra showed a shift to longer wavelengths and an enhancement of the absorption in the visible region(＞400 nm)for the C,N-codoped TiO2,compared to the pure TiO2,C-doped TiO2 and N-doped TiO2.The C,N-codoped TiO2 showed the best photocatalytic activities for the degradation of methyl orange under visible light irradiation.and was a promising photocatalyst for utilizing the solar energy.关键词
