摘要：Egg-shell-type Ag/SiO2 pellet catalysts with various Ag-shell thicknesses, in which the structures of Ag active sites are similar, are controllably synthesized for exploring the diffusion effects on DMO hydrogenation to MG. The egg-shell-type pellet catalyst with an optimized thickness of the Ag-shell exhibits enhanced hydrogenation activity and MG selectivity.
