Catalytic Hydrogen Generation from Ammonia Borane and Sodium Borohydride
This research community focuses on developing catalysts that release hydrogen gas through the hydrolysis of chemical hydrides, specifically ammonia borane and sodium borohydride, for use in portable fuel systems and energy storage applications.
The work centers on designing heterogeneous catalysts, frequently involving nanoparticles of cobalt, nickel, platinum, ruthenium, or palladium, often supported on carbon, metal oxides, or metal-organic frameworks. The primary objective is to enhance the rate and efficiency of hydrogen evolution while maintaining catalyst stability and reusability. Recurring methods include the synthesis of bimetallic alloys, single-atom catalysts, and nanostructured supports to optimize the interaction between the catalyst surface and the hydride molecules. The research consistently addresses the kinetic challenges of hydrolytic dehydrogenation, aiming to make the process viable for practical hydrogen storage and release in liquid-phase systems.
The community is most heavily represented in hydrogen research, accounting for 70.0% of all tracked hydrogen studies, and in nitrogen research, comprising 30.0% of that element's output. It also constitutes 40.0% of sodium research and 30.0% of cobalt and boron research.
The community comprises 5,529 papers, with the highest publication volume in the International Journal of Hydrogen Energy, followed by the Journal of the American Chemical Society and the Journal of Power Sources.
Recent work continues to explore novel catalyst architectures, including green-synthesized nanocatalysts, metal-organic frameworks, and atomically engineered interfaces, to improve the efficiency and sustainability of hydrogen production from these chemical hydrides.
