A selective synthesis of acetic acid from syngas over a novel Rh nanoparticles/nanosized SiO2 catalysts

A novel Rh nanoparticles/nanosized SiO2 catalyst was prepared using microemulsion technique and grinding method. The total selectivity of acetic acid and ethyl acetate in the oxygenate products of CO hydrogenation on this catalyst could reach 74.8%.
