Modulating N−H Bond Cleavage in Catalytic Ammonia Oxidation Reaction

Abstract The ammonia oxidation reaction (AOR) exhibits significant potential for environmental remediation and energy utilization. Nevertheless, the complex reaction mechanism of the AOR poses numerous challenges to its application. To overcome these challenges and realize an efficient AOR process, a thorough understanding of every elementary reaction step, especially the cleavage of N−H bonds, is crucial. This review delves into the influence of N−H bond cleavage on the rate and selectivity of AOR, and summarizes the latest advancements in promoting this crucial step. Furthermore, we discuss the challenges faced by N−H bond cleavage and provide insights into the design of efficient catalytic AOR systems.
