The production of gluconic acid from D ‐glucose represents an attractive target for industry. In this work, we propose an efficient, eco‐friendly, and selective method to oxidize D ‐glucose with aqueous H 2 O 2 in the presence of FeSO 4 as a catalyst. The reaction was improved significantly under ultrasonic (US) activation, which led to excellent yields in only a few minutes. In addition, we determined that the reaction occurred through a sono‐Fenton process by studying the production of hydroxyl radicals and optimizing the experimental conditions of the reaction. The energy consumption of the process was also investigated in this study.
