Preparation and Application of Mesoporous Alumina

本文介绍了介孔氧化铝(MA)的各种制备方法,概括了MA制备的分析表征方法,如TEM、SAED、XRD、LAXRD、气体吸附-脱附、DT-TGA等。通过平均孔径、比表面积、MA形貌等因素,讨论和总结了制备方法、铝源、模板剂、反应物配比、pH值和后处理方法等对MA制备和热稳定性的影响,综述了近年来MA的研究和应用进展,并对今后的研究方向进行了展望。

This paper has reviewed recent progress in preparation,characterization and application of mesoporous alumina（MA）.We introduce the preparation methods of MA contrastively and respectively,and overview the post treatment method of precursors.Subsequently,by contrasting the average pore size,specific surface areas and morphology of MA,we discuss the influence factors on the preparation and thermal stability of MA,which involve preparation method,aluminum sources,template,reactant ratio,pH value,post treatment method of precursors and so on.In addition,analysis and characterization methods utilized in preparation of MA,including transmission electron microscopy（TEM）and selected area electron diffraction（SAED）,X-ray powder diffraction（XRD）and low angle X-ray powder diffraction（LAXRD）,gas adsorption-desorption method,different thermal and thermo gravimetry analysis（DT-TGA）and 27 Al magic angle spinning nuclear magnetic resonance（27 Al MAS NMR）,are introduced in detail.Meanwhile,the development trend of preparation and application of MA for the field of catalytic,adsorption,optics and other fields is prospected.
