摘要
Glycerol,as a byproduct of biodiesel production,can be used to produce a variety of high-value C_(1),C_(2),and C_(3)chemicals by electrocatalytic glycerol oxidation reaction(EGOR).Further coupling EGOR with CO_(2)reduction reaction(CO_(2)RR)or hydrogen evolution reaction(HER)in paired electrolyzers is increasingly attractive due to the reduced input energy for the simultaneous formation of value-added products on both sides of the cell.This review article introduces the main reaction path of EGOR and the influencing factors of the reaction conditions of EGOR.The catalysts for the highly selective formation of glyceric acid,lactic acid,tartaric acid(TA),or formic acid(FA)from EGOR are highlighted.The latest research progress on design strategies of catalysts required for these reactions was reviewed.Subsequently,the paired electrolyzers coupling EGOR with HER or electrocatalytic CO_(2)RR were evaluated.Finally,the challenges and prospects in the field of EGOR are pointed out to move forward with the future development of glycerol electrocatalysis.
