Fabrication of MOF-based composite for synergistic catalysis

Heterogeneous catalyst has received extensive attention in the field of chemical industry due to its high activity and selectivity[1-2].In general,the heterogeneous catalysts exhibit certain advantages,such as large surface area,more exposed active sites,and easily recovery[3].For example,noble metal nanoparticles(NPs)were uniformly supported by the porous materials(e.g.,porous carbon,zeolite,and silica)for preparing the heterogeneous catalysts[4-6].During the cyclic catalysis reaction,however,the catalyst may adhere to the centrifugal tube when centrifugation,resulting in the loss of catalyst and affecting the catalytic performance[7].To overcome this problem,the reasonable fabrication of heterogeneous catalysts with easy recovery process is of great importance to obtain their high cycling catalytic activity.
