Abstract

Rh nanoparticles (2-4 nm) confined in the nanopores (6.5 nm) of ordered mesoporous carbon (OMC) were characterized by scanning transmission electron microscopy imaging on the cross-section of OMC grains generated using state-of-the-art focused ion beam lift-out technique. The catalytic activity (turnover frequency) and ethanol selectivity of Rh/OMC for synthesis gas conversion to ethanol are enhanced greatly when triply promoted with Mn, Li, and Fe oxides. Compared with traditional mesoporous silica having similar pore size, OMC as the support of promoted Rh catalyst increases the ethanol selectivity along with suppressing the formation of undesired hydrocarbons, although its overall activity is lowered to some extent.
