Abstract
This paper focuses on the electrocatalytic oxidation process conditions of glycerol, a by-product in the preparation of biomass resources, aiming to develop an efficient glycerol conversion method to enhance its added value and thereby improve resource utilization. In this paper, the effects of key factors such as catalyst types, reaction potential, and acidity/alkalinity of the electrolytic cell on glycerol conversion rate and product selectivity have been explored. The optimized process conditions can significantly increase the glycerol conversion rate and obtain high-value-added products. For instance, by designing the interface structure of the metal surface and the alkalinity of the catalyst, the conversion rate of glycerol and the yield of glyceric acid were 87.6% and 58.6%, respectively. This study provides a theoretical basis for the practical application of efficient conversion of glycerol electrocatalysis, which is of great significance for promoting the development of the renewable energy.
Key words： Biodiesel; Glycerol; Catalytic process; Selective oxidation; High added value
