Abstract γ‐Mo 2 N catalysts exhibit excellent activity and stability in ammonia decomposition reactions. However, the influence of oxygen on its is still unknown. In this work, two with different content are synthesized using temperature‐programmed nitridation α‐MoO 3 . The highly oxidized their performance closely related to content. high (HO‐γ‐Mo N) much higher, whose H formation rate at 550 °C 3.3 times higher than low (LO‐γ‐Mo N). This mainly attributed aspects: one hand, valence state Mo HO‐γ‐Mo leads stronger Mo─NH bonds, which promotes adsorption activation NH On other generated by N─H bond breaking more easily migrated O, avoids excessive occupying active sites alleviates negative effect hydrogen poisoning.
