摘要
含强L酸中心的Sn-Beta沸石在生物质平台化合物转化中表现出独特的活性和选择性,具有广阔的应用前景。Sn-Beta沸石主要合成方法有干胶法、水热法和同晶取代法。不同方法制备的Sn-Beta沸石Sn活性位的微环境及酸性质存在差异,在反应中表现出不同的反应性能。主要介绍Sn-Beta沸石合成方法及控制合成的影响因素。
Sn-Beta zeolite with strong Lewis acid site exhibits unique activity and selectivity in conversion of biomass derived platform compounds,and shows a bright prospect.Dry gel conversion method, hydrothermal synthesis method and isomorphous substitution method are the typical synthetic methods for Sn-Beta zeolite.The microenvironment of Sn active sites and the corresponding acidic properties of Sn-Beta zeolites from above methods are different, leading to different catalytic performance.Here, advances in synthetic methods for Sn-Beta zeolite and control factors of synthesis were introduced.
