Abstract
The direct synthesis of dimethyl carbonate from methanol and CO2 is particularly attractive as it provides a green alternative to other routes while allowing CO2 conversion.
Highlights
Among organic carbonates, dimethyl carbonate (DMC) is a promising green chemical because of its low toxicity and rapid biodegradability 12 Its versatile chemical properties account for its wide use as an agent in carbonylation and methylation reactions, replacing DMSO, COCl2 and CH3X 34 It is largely used as a precursor for the production of polycarbonates and polyurethanes
The present work describes a robust method for measuring catalytic activity for DMC synthesis from methanol and CO2 far from equilibrium conditions
By selecting the most active composition of ceria-zirconia samples and further exploring different synthesis approaches, we found that the synthesis of mixed ceria-zirconia oxides by flame spray pyrolysis yielded the most active catalysts reported so far
