Abstract

Mass transfer phenomena significantly influence the conversion rate and product distribution in the 5-hydroxymethylfurfural (HMF) electrochemical reduction to value-added products. This study proposes a cost-effective approach to enhance the production rate and selectivity toward 2,5-bis(hydroxymethyl)furan (BHMF) as the target product. Cocirculating the electrolyte with an inert gas across the electrode surface increases the conversion rate and selectivity toward alcohol formation by 50% and 75%, respectively. This improvement is attributed to enhanced reactant adsorption and product desorption, along with improved mobility of forming H2microbubbles away from the surface, which increases the availability of active sites for the hydrogenation reaction. Simulations of the hydrodynamic behavior of the electrolyte near the working electrode during gas purging suggest improved convection near the electrode.
