作者简介：

Prof. Feng-Shou Xiao received his B.S. and M.S. degrees in the Department of Chemistry, Jilin University, China. From there he moved to Dalian Institute of Chemical Physics, China for Ph. D. research, then to the Catalysis Research Center, Hokkaido University, Japan, where he was involved in collaborative research between Dalian Institute of Chemical Physics & Jilin University, China with Hokkaido University, Japan. Since the end of 2009, Dr. Xiao as a distinguished professor has moved to Department of Chemistry, Zhejiang University. Currently, he is an associate editor of Industrial & Engineering Chemistry Research, also serving as secretary of the Asia-Pacific Association of Catalysis Societies. His research is mainly focused on zeolites, porous materials, and catalysis. He has more than 400 peer-reviewed papers with over 13 000 citations, ~ 50 granted patents, and over 40 plenary and keynote lectures at international conferences.

报告摘要：

Zeolites have been widely used as heterogeneous catalysts in petrochemical and fine chemical industry, but their syntheses are not sustainable because of using costly and toxic organic templates and a huge amount of water under hydrothermal conditions. In addition, the synthesis of mesoporous zeolites from “soft-templating” strategy normally requires designable mesoscale templates with relatively high cost, which strongly limits their industrial applications. In this talk, it is briefly summarized our recent sustainable and generalized routes for synthesis of zeolites. Furthermore, by employing these new strategies for synthesis of zeolites, it is successfully prepared core-shell structured metal and metal oxide@zeolite catalysts, which combine the advantages of both zeolite shape selectivity and metal high activity in catalytic reactoins. For example, a manganese oxide catalyst with zeolite sheath (MnOx@S-1), which exhibits high selectivity for producing nitriles by efficiently facilitating the oxidative cyanation; when photocatalyst TiO2 is fixed inside of zeolite crystals, it is given ideal performances for the selective degradation of pollutants but are harmless to the organisms; when Pd nanoparticles are encapsulated inside of zeolite crystals, it is shown high furan selectivity in the hydrogenation of biomass-derived furfural .
