AI Technical Summary
In existing technologies, the preparation methods of gluconic acid have problems such as long oxidation time, easy catalyst deactivation, low product purity, high cost, and poor selectivity, making it difficult to achieve efficient, green, and sustainable electrocatalytic synthesis.
Using a Pd single-atom catalyst, a Pd single-atom catalyst was prepared by combining a hydrothermal treatment and reflux reaction of molybdenum oxide nanoribbons loaded with Pd single atoms. The catalyst was then applied to the electrode to form Mo-O-Pd interfacial chemical bonds, achieving highly selective and stable electrocatalytic oxidation to gluconic acid.
It achieves near 100% atom utilization with extremely low Pd loading, gluconic acid formation selectivity of over 85%, high Faraday efficiency, excellent catalyst stability, and long lifespan, making it suitable for industrial applications.
