A safe and efficient approach for hydrogen storage and generation to enhance the development of hydrogen economy
Hydrogen is one of the most important sources of green energy. The issues of safe storage, delivery and efficient release of hydrogen have become longstanding technical barriers that limit its widespread utilization. The novel catalysis devices developed in this project could solve pivot issue, avoiding the potential risks in those based on liquification or pressurized vessels.
The technique is based on the most promising solid-state hydrogen storage materials, ammonia borane, and its hydrolysis as catalyzed by multicomponent transition-metal phosphides. The graphene-aerogel tubes embedded with multicomponent transition-metal phosphides are catalysis units, which have ultra-fast kinetics of hydrogen generation during the hydrolysis of ammonia borane after optimization.
The catalysis devices for hydrogen generation are safe, efficient and facile, facilitating the utilization of hydrogen energy in fuel-cell vehicles, ships and in power plants. Prototypes of hydrogen storage and generation based on ammonia borane and the catalysis devices will be built, and could be further integrated as a compact hydrogen source for hydrogen fuel cell vehicles.
