Abstract:

Urea oxidation reaction(UOR) is a widely recognized sustainable clean energy technology,which is expected to become an effective process for treating urea-containing wastewater and converting it into energy.Compared to the high-energy-consuming oxygen evolution reaction(OER),UOR exhibits a lower thermodynamic potential,suggesting its potential as an alternative to OER.Urea,as a stable multifunctional substance,especially exhibits good stability at ambient temperature and is considered a potential alternative to hydrogen in fuel cells.However,UOR involves complex intermediate adsorption/desorption processes,necessitating efficient catalysts.Through morphological engineering,alloy effects,and atomic doping,microstructure-controlled modified catalysts can achieve exceptional UOR performance.Although there is an abundance of research and reviews on microstructure-controlled catalysts,this review is aimed to systematically summarize the cutting-edge design strategies of microstructure-controlled catalysts and their applications in electrocatalysis,exploring how to optimize the structure and function of catalysts by different strategies,thereby enhancing their performance in UOR.

Key words: urea oxidation reaction, oxygen evolution reaction, electrocatalysis, direct urea fuel cell
