Effect of pore structure on catalytic properties of mesoporous silica supported rhodium catalysts for the hydrogenation of cinnamaldehyde

- We prepared porous silica supported Rh catalysts via scCO2 impregnation.
- Rh particle size was strongly influenced by calcination condition.
- Rh/MSU-H(673) showed high catalytic activity for cinnamaldehyde hydrogenation.
