| 摘 要： | 通过液晶模板机理合成了Al-MCM-41介孔分子筛,并用磷酸浸渍法制备PO43-/Al-MCM-41.通过X射线衍射(XRD)、氮气吸附-脱附、红外光谱、Hammett指示剂胺滴定等方法对所合成样品进行了表征.XRD和N2吸附脱附研究结果表明.PO43-/Al-MCM-41具有较规则的孔道结构.平均孔径3.10 nm,比表面积为560 m2/g.酸量滴定分析表明,PO43-/Al-MCM-41具有较强的酸性.

| Abstract: | PO43-/Al-MCM-41 was obtained by impregnating Al-MCM-41 in phosphonic acid.The mesoporous materials,viz.Al-MCM-41 and PO43-/Al-MCM-41 were characterized using several techniques,e.g.powder X-ray diffrac-tion(XRD),nitrogen adsorption measurements,Fourier transform-infra red spectroscopy(FT-IR) and Hammett measurements.XRD,nitrogen adsorption-desorption studies indicated that PO43-/Al-MCM-41 had ordered hexagonal framework structure and average pore diameter of 3.10nm nm and 560 specific surface area.Hammett i... |
