Electronic state,abundance and microenvironment modulation of Ru nanoclusters within hierarchically porous UiO-66(Ce)for efficient hydrogenation of dicyclopentadiene
Developing catalysts for dicyclopentadiene(DCPD)hydrogenation to tetrahydrodicyclopentadiene(THDCPD)at low temperature is crucial and challenging for the green and energy-saving produc-tion of high energy density aviation fuel.Herein,hierarchically porous UiO-66(Ce)encapsulate Ru nanoclusters(NCs)was successfully customized by soft template method and in-situ reduction.The mesoporous UiO-66(Ce)promoted the high dispersion of Ru NCs,and the transfer of substrate molecules.By controlling the synthesis conditions,the electronic state,abundance,and microenvi-ronment of Ru NCs were precisely regulated.Theory calculation and experimental results revealed that metallic Ru as the main active sites greatly promoted the adsorption and activation of substrate molecules.Therefore,mesoporous UiO-66(Ce)encapsulated Ru NCs showed remarkable catalytic DCPD hydrogenation performance with DCPD conversion of 100％and THDCPD selectivity of-100％(60 ℃,only 35 min).This study has brought new inspiration and guidance to the rational design of function materials for various catalytic applications.
