Novel Fe‐modified CeO2 Nanorod Catalyst for the Dimethyl Carbonate Formation from CO2 and Methanol

Abstract

AbstractA series of Fe‐modified CeO2 catalysts with nanoparticle, nanorod, nanocube and nano‐octahedron morphologies were synthesized and applied for direct synthesis of dimethyl carbonate (DMC) from CO2 and methanol. The Fe‐modification shows a remarkably promoting effect on the formation of DMC over Fe‐modified CeO2 nanorod. The DMC yield was improved from 0.202 to 2.568 mmol DMC per gcat by 2 %Fe‐modification of CeO2 nanorod. A synergistic effect among the moderate acid‐basic sites, specific surface area and surface composition resulted from Fe‐modification was proposed to be crucial to obtaining the high reactivity of DMC formation.
