| 摘 要： | 以聚乙二醇(PEG)为模板剂、正硅酸乙酯(TEOS)为硅源,采用溶胶-凝胶法合成了铜掺杂介孔硅铝氧化物复合材料,并通过N2等温吸附-脱附法、X射线衍射、红外光谱等测试对产物进行表征,考察了PEG质量、分子量以及CuO掺杂量对复合材料孔结构的影响.结果表明:加入PEG能够明显增加复合材料的比表面积,随PEG质量增大,介孔孔容增多,孔径分布较均匀,加入24 g PEG时比表面积增加一倍达到约500 m2.g-1.PEG的分子量为600～2 000时样品以4 nm介孔为主,而分子量为10 000时,样品以小于2 nm的微孔为主.

| Abstract: | Cu-doped mesoporous silica-aluminia composite was prepared by sol-gel method,using TEOS as silica source and PEG as template.The effect of PEG mass,molecular weight,and CuO wt% on the textural structure composite was characterized by N2 adsorption-desorption isotherm,X-ray diffraction(XRD),and Fourier transform infrared(FT-IR).The results showed that the specific surface area of samples increased obviously using PEG as template.The specific surface area of samples increased double to 500 m2 g-1 using 24 g P... |
