| Summary: | Production of hydrogen by catalytically hydrolyzing ammonia borane (AB) has attracted extensive attention in the field of catalysis and energy. However, it is still a challenge to develop a both inexpensive and active catalyst for AB hydrolysis. In this work, we designed a series of MoO3-doped MnCo2O4 (x) catalysts, which were fabricated by a hydrothermal process. The morphology, crystalline structure, and chemical components of the catalysts were systematically analyzed. The catalytic behavior of the catalyst in AB hydrolysis was investigated. Among these catalysts, MoO3-doped MnCo2O4 (0.10) microspheres composed of nanosheets exhibited the highest catalytic activity. The apparent activation energy is 34.24 kJ mol−1 and the corresponding turnover frequency is 26.4 molhydrogen min−1 molcat−1. Taking into consideration the low cost and high performance, the MoO3-doped MnCo2O4 (0.10) microspheres composed of nanosheets represent a promising catalyst to hydrolyze AB for hydrogen production.
