摘要
Shape selectivity is one of the most exiting topics in catalysis. However, most reported shape selectivity in catalysis occurred in gas phase reactions, especially in petro chemistry using zeolites as catalysts. However, it is still quite intriguing and difficult to control shape selectivity in liquid solutions. Using nanoporous structures, we are able to generate core shell type structures, in which the active sites are embedded inside the porous shells, so that the pore structure of the shell(silica, carbon based) may incur certain restriction(selectivity) on the size of the reaction species that can diffuse through the shell. Three types of shells were developed: zeolite shell, mesoporous shell, MOF shell, and sharp shape selectivity were observed for hydrogenation reaction, condensation reactions and Suzuki coupling reactions.
