| الوصف: | Developing low-cost and highly active hydrolysis catalytic materials for the dehydrogenation of hydrogen-rich chemicals is a promising strategy to store and easily release hydrogen for fuel cell applications. In this study, new bimetallic hybrid nanoplates containing Co3O4 and CuCoO2 were developed via a facile and low-cost approach for catalytically producing hydrogen from ammonia borane (NH3BH3). The as-prepared efficient Co3O4–CuCoO2 material was employed as a catalyst for NH3BH3 hydrolysis, and it exhibited a high catalytic performance with a turnover frequency (TOF) of 65.0 molhydrogen molcat.−1 min−1 at room temperature. The results revealed that the hybrid Co3O4–CuCoO2 catalysts exhibited much improved catalytic activity towards the hydrolysis reaction in contrast to the individual Co3O4 and CuCoO2 catalysts. A kinetic study showed that the Co3O4–CuCoO2 catalytic material had superior activity with an apparent activation energy (Ea) of 20.5 kJ mol−1, which was found to be one of the lowest Ea for NH3BH3 hydrolysis ever reported in the literature. This work provides a promising approach for the synthesis of noble metal-free catalysts exhibiting high catalytic activity towards NH3BH3 hydrolysis. |
