铈-氟-纳米二氧化钛光催化剂的制备及光催化性能研究
Preparation of nano-TiO2 doped with Ce,F and its performance for photocatalytic degradation of organic pollutions
摘要
Abstract
Preparation of the photocatalyst ,nano‐doped with Ce and F ,using TiCl4 ,Ce(NO3 )4 and N H4 F by modified sol‐gel method .Crystal form ,surface morphology ,elements and opti‐cal absorption of the ternary photocatalyst and nano‐TiO2 commercially available were char‐acterized by XRD ,SEM ,EDS and UV‐vis DRS .Under the effect of photocatalysts ,the deg‐radation rate of methyl orange was tested by UV‐vis spectroscopy .The results indicated some phenomenon as follows .Compared with pure TiO2 ,there appears minor phase and trace phase in ternary photocatalyst ;There are structure of multilateral block in the particles of ternary photocatalyst ;ternary photocatalyst responded to wider wavelength of light ;And the degradation efficiency of methyl orange was higher .The experiment showed that the degra‐dation of methyl orange was in accordance to pseudo‐first‐order process .From the above , the mechanism of the photocatalytic degradation was explored .关键词
