High Voltage Driven MnO2/CuO for Efficient Oxidation of 5-Hydroxymethylfurfural

Abstract

5-hydroxymethylfurfural oxidation (HMFOR) by electrocatalysis is a promising method for producing 2,5-furandicarboxylic acid (FDCA). Because of the competitive side reaction, it is still a challenge to promote the current density and Faraday efficiency of FDCA at high voltage. In this work, MnO2/CuO was successfully fabricated, of which Faraday efficiency remains 98.2% (72.12 mA/cm2) at 1.6 VRHE and 80.2% even at 1.7 VRHE. Therefore, this work provides a novel approach for breaking the limitation of high voltage for FDCA production.
