氧化钛纳米管催化剂薄膜背光催化的研究

Research on Background Irradiated of TiO_2 Nanotube Thin Films

本文采用水热法制备了氧化钛纳米管催化剂薄膜,建立了背光催化数学模型,讨论了薄膜厚度和光源波长对背光催化的影响,并进行了实验验证。结果表明:当催化剂薄膜厚度为dopt,且对应选择光源波长为λopt时,背光催化效率ηb达到最佳ηb(dopt)。该研究对光催化工业化推广应用具有重要意义。

TiO2 nanotube thin films was synthesized via hydrothermal process, the effects of thickness of the film and the wavelength of the light source on the background photocatalysis were discussed. The results show that in background photocatalysis, which can improve the catalyst＇s photocatalytie activities, there is an optimal thickness of the film according to the wavelength of the light source. These results are useful for the design of photocatalytic reactors.
