Abstract
Abstract A novel SiO 2 synthesized by the Stober method was studied as the support for Rh–Mn–Li catalyst, and better performance for C 2 oxygenate synthesis via CO hydrogenation was achieved compared with the counterpart using commercial SiO 2 as the support. The investigation based on the catalytic performance and characterizations of the catalysts suggests that the hydroxyl–metal interaction over the catalyst supported on SiO 2 prepared by the Stober method results in a change in the CO adsorption on Rh particles, which promotes the CO dissociation and CO insertion, leading to higher CO conversion and C 2 oxygenate selectivity.
