Abstract
Electrochemical aromatic chlorination reaction (E-ACR) represented by electrocatalytic chlorination of anisole (ANI) is a promising and economical strategy due to its mild reaction conditions and environmental friendliness. However, exploring advanced non-precious metals E-ACR electrocatalysts remains a great challenge. Herein, we synthesized Fe2O3-X nanoparticles (Fe2O3-X NPs, where X represented calcination temperature) integrating with crystal facet effect for efficiently electrochemical converting ANI into para-chloroanisole (4-CANI). Among them, Fe2O3-400 NPs shows significantly improved E-ACR catalytic activity, featured with average 48 % of Faradaic efficiency (FE) and maximum 73 % of selectivity of 4-CANI at 2.4 V. Analyses indicate that the performance of Fe2O3-X NPs is positively correlated with the intensity of (400) facet, and the (400) fact can optimize the adsorption of the *C6H5OCH3 and *C6H4OCH3 intermediates to improve conversion efficiency of 4-CANI. This work highlights the crystal facet‐performance relationship of catalysts for E-ACR and gives critical insights into the effect of crystal structure for nanomaterials on E-ACR.
