Abstract
Section titled âAbstractâAbstract Electrocatalytic oxidation of 5âhydroxymethylfurfural (HMF) offers a renewable approach to produce the valueâadded platform chemical 2,5âfurandicarboxylic acid (FDCA). The key for the economic viability of this approach is to develop active and selective electrocatalysts. Nevertheless, a reliable catalyst evaluation protocol is still missing, leading to elusive conclusions on criteria for a highâperforming catalyst. Herein, we demonstrate that besides the catalyst identity, secondary parameters such as materials of conductive substrates for the working electrode, concentration of the supporting electrolyte, and electrolyzer configurations have profound impact on the catalyst performance and thus need to be optimized before assessing the true activity of a catalyst. Moreover, we highlight the importance of those secondary parameters in suppressing side reactions, which has long been overlooked. The protocol is validated by evaluating the performance of freeâstanding Cuâfoam, and CuCoO modified with NaPO 2 H 2 and Ni, which were immobilized on boronâdoped diamond (BDD) electrodes. Recommended practices and figure of merits in carefully evaluating the catalyst performance are proposed.
