摘要: 以SiO₂为成核中心,钛酸四丁酯为钛源,分别以多羟基化合物乙二醇、丙三醇、葡萄糖和聚乙烯醇为联接剂,采用水解沉淀法制备了碳掺杂和包覆的多孔SiO₂/TiO_2-xC_x/C可见光响应型光催化剂。采用X-射线衍射(XRD)、透射电子显微镜(TEM)、X-射线光电子能谱(XPS)、傅里叶变换-红外光谱(FTIR)、比表面积(BET)和紫外-可见(UV-Vis)漫反射光谱对样品进行表征。对不同结构样品的形成机理进行了分析。以次甲基蓝(MB)溶液为模拟废水,对样品的吸附性能和可见光催化性能进行了评价。结果表明,多羟基化合物对材料的结构和性能有重要影响。碳的掺杂和包覆使材料的吸收光谱包含了整个可见光区,而多孔结构使材料的吸附性能得到提高。以聚乙烯醇为原料所得样品吸附性能最好,30 min内吸附率达到70%;而以丙三醇为原料所得样品具有最好的可见光催化性能,40 min内次甲基蓝的降解率达到95%。

Abstract: We report an architecturally controlled synthesis of porous SiO₂/TiO_2-xC_x/C composites with high adsorption capability and efficient visible-light photocatalytic activity. The porous composites are composed of silica particles as the cores and tetrabutyl titanate as the precursor for the TiO₂ shell. Ethylene glycol, glycerol, glucose and polyvinyl alcohol were used as the binding agent between the core and the precursory shell, the carbon source and the porosity promoter, respectively. The structure, crystallinity, morphology, and other physical-chemical properties of the samples were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), high-resolution transmission electron microcopy (HRTEM), X-ray photoelectron spectroscopy (XPS), fourier transform-infrared spectroscopy (FTIR), N₂ adsorption-desorption isotherms measurements and UVVis diffuse reflectance spectroscopy (DRS). The formation mechanism of the porous composites was discussed. Methylene blue solution(MB) was used as model wastewater to evaluate the adsorption and photocatalytic activity of the samples under visible light. The as-synthesized porous composites exhibit both much higher adsorption capability and better photocatalytic activity for the photooxidation of MB than that of the pure silica-titania composite. The adsorption rate reaches 70% within 30 min when polyvinyl alcohol is used as the carbon source, and the sample using glycerol as the carbon source has the best visible- light photocatalytic activity and the degradation rate of MB can be 95% within 40 min.
