Abstract
Abstract A series of Fe‐modified CeO 2 catalysts with nanoparticle, nanorod, nanocube and nano‐octahedron morphologies were synthesized and applied for direct synthesis of dimethyl carbonate (DMC) from CO 2 and methanol. The Fe‐modification shows a remarkably promoting effect on the formation of DMC over Fe‐modified CeO 2 nanorod. The DMC yield was improved from 0.202 to 2.568 mmol DMC per g cat by 2 %Fe‐modification of CeO 2 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.
