| 摘 要： | 采用铝阳极氧化法和浸渍法制备出新型SO42-/Al2O3-Al固体酸催化剂,通过BET,XRD,XPS等物性表征,考察了阳极氧化时间、焙烧温度等对催化剂制备的影响。BET结果表明,催化剂的比表面积要小于载体Al2O3的比表面积;XRD结果表明,载体Al2O3为无定形结构,且负载SO42-后,催化剂的物相结构没有发生改变;XPS结果表明,催化剂表面主要由SO42-和Al2O3组成。活性评价表明,该催化剂对酯化反应具有较好的催化活性。

| Abstract: | A new solid acid catalyst was prepared by supporting SO~(2-)_4onto a thin alumina film that had been formed by anodic oxidation of high-purity aluminium foils.The characters of the prepared(catalyst) were figured out in the term of BET,X Ray Diffraction(XRD) and X Photoelectron Spectra(XPS).The result showed that specific surface area of the catalyst was much smaller than that of the oxide which had not undergone the sulfate treatment.X Ray Diffraction(XRD) demonstrated the(supporter) Al_2O_3 layer was in amorphous configuration and the structure of the catalyst was not changed after loading SO~(2-)_4.X-ray Photoelectron Spectroscopy(XPS) showed the catalyst surface is composed of SO~(2-)_4and Al_2O_3.The catalyst also showed higher activity for esterification. |
