Preparation of Ti supported Co film composed of Co nanofibers as catalyst for the hydrolysis of ammonia borane

In this work, Co film composed of Co nanofibers supported on Ti substrate was prepared by a magnetic-field-assisted deposition process. The as-prepared Ti supported Co film exhibited high catalytic activity in the hydrolysis of ammonia borane with apparent activation energy of 28.0 kJ mol(-1), which is much lower than that of many Co-based nanocatalysts reported in literature. Also, it displayed improved durability and reusability in contrast to many powdery Co-based nanocatalysts. Its high performance renders it as a strong catalyst candidate in the field of chemical hydrogen-storage, which can be applied in the hydrolysis of ammonia borane for hydrogen generation.
