Abstract:

Glycerol is an important by-product in the production process of biodiesel with low prices and abundant reserves.Converting glycerol into high value-added fine chemicals is one of the effective ways to alleviate the current problems of resources and environment.Glycerol electrooxidation reaction(GEOR) has great application prospects due to its advantages of no need for oxidants and generation of clean energy H2 at the cathode.However,the high cost and scarcity of precious metal catalysts limit their commercial application.Therefore,there is an urgent need to develop efficient non-noble metal catalysts to replace noble metal catalysts.Based on a brief introduction of glycerol oxidation mechanism,recent research on transition metal-based GEOR catalysts and various catalyst design strategies to enhance glycerol oxidation performance were reviewed.These strategies included doping engineering,alloy strategies,heterogeneous structure building,composite engineering and crystal phase adjustment.Finally,the challenges faced by transition metal-based catalysts in GEOR were prospected.

Key words: glycerol, oxidation, electrocatalysis, non-noble metal
