CeZrO _4‐δ a Robust Fluorite Catalyst for Solvent‐Free Transesterification of Ethylene Carbonate to Dimethyl Carbonate

The current work involves the preparation, characterization, and application of zirconia‐doped bimetallic oxide (CeZrO _4‐δ ) as an efficient catalyst for the transesterification of ethylene carbonate (EC). In this study, we report fluorite CeZrO _4‐δ as a highly active, durable, and reusable catalyst for converting EC to dimethyl carbonate. The catalysts were prepared using a gel combustion method, followed by calcination, and then subjected to catalytic activity tests. The prepared catalyst was thoroughly characterized using various physicochemical techniques. Additionally, the catalyst can be recycled and reused up to six runs with minimal loss of reactivity. Both fresh and recycled catalysts were analyzed using several methods, including X‐ray diffraction, X‐ray photoelectron spectroscopy, transmission electron microscopy, Raman analysis, ICP‐OES, and Brunauer–Emmett–Teller (BET) analysis. The use of earth‐abundant, recyclable mixed‐metal oxide catalysts highlights the environmentally benign nature of this approach.
