  • 摘要: 以十六烷基三甲基溴化铵（CTAB）和氟化钠分别为碳源和氟源，采用溶胶-凝胶法制备了CF-TiO2 光催化剂，并对其进行了SEM、XRD、N2吸附、XPS、UV-visDRS和PL表征。研究了CF-TiO2在模拟太阳光下光催化降解亚甲基蓝溶液的活性，并讨论了氟掺杂量以及CTAB加入量对催化性能的影响。结果表明，CF-TiO2为锐钛矿型，孔结构丰富、比表面积大，氟碳共掺后使TiO2光催化剂的禁带宽度变窄为2.40 eV，在可见光区吸收增强，有效提高TiO2在模拟太阳光下的光催化活性，而且当n（F/Ti）（氟钛摩尔比）为0.1，加入碳源CTAB量为2 g时，其光催化活性最好。
    Abstract: CF-TiO2 catalyst were synthesized by sol-gel method with cetyl trimethyl ammonium bromide (CTAB) as carbon resource and fluorol (NaF) as fluorine resource and characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD),N2 sorption,X-ray photoelectron spectroscopy (XPS),UV-Vis diffuse reflectance spectroscopy (UV-Vis DRS) and photoluminescence (PL).The photocatalytic activities of CF-TiO2 for the degradation of methylene blue (MB) were investigated under simulated sunlight irradiation,and the effects of amount of CTAB and NaF on catalytic performance were also discussed.The results indicated that CF-TiO2 is anatase,it has porous structures and large specific surface area.It was demonstrated that the carbon and fluorine co-doped TiO2 narrow the band gap to 2.40 eV,extend the photoresponse into visible light region and exhibit a superior photocatalytic activity under simulated sunlight irradiation.CF-TiO2 (n(F/Ti)=0.1,2 g CTAB) show the best photocatalytic activity.
