“…When it comes to electrode materials, gold − and platinum − have been found to be the most promising. Recently, composite materials of different noble metals − as well as nonprecious metal catalyst − have been reported for the electrooxidation of glucose. The latter also alleviates the need for precious, rare materials.…”

Converting glucose electrochemically to its valuable derivatives, gluconic and glucaric acids, is a promising process for the utilization of renewable carbon sources. Understanding the reaction pathway to form glucaric acid from glucose is key to performing the process efficiently. In this study, we investigate the influence of mass transport as well as electrode potential on the product distribution in glucose, gluconic acid, and glucuronic acid oxidation on a gold disk in an RDE setup. We find glucose and glucuronic acid to be easily oxidized, while the oxidation of gluconic acid is kinetically limited. Combining DFT calculations and the experimental results, we show that on gold, the oxidation of aldehyde groups proceeds readily, while the oxidation of hydroxyl groups is challenging and occurs indiscriminately on C atoms in glucose and its derivatives. Additionally, the DFT calculations present a reaction pathway that can explain the absence of glucuronic acid in the conducted experiments.
