Three dimensional Ag/KCC-1 catalyst with a hierarchical fibrous framework for the hydrogenation of dimethyl oxalate

The novel fibrous nano-silica (KCC-1) based silver nanocatalyst exhibits excellent catalytic activity with a high TOF value (53.2 h(-1)) in the gas-phase hydrogenation of DMO to MG. Compared with the traditional mesoporous silica materials, KCC-1 remarkably enhances the accessibility of the silver active sites due to its three dimensional hierarchical channel structure.
