Catalytic Hydrogen Generation from Ammonia Borane and Sodium Borohydride
This research community focuses on the chemical release of hydrogen gas from liquid-phase storage materials, specifically ammonia borane and sodium borohydride, using heterogeneous catalysts.
The work centers on developing efficient catalysts to drive the hydrolysis and dehydrogenation of these chemical hydrides. Recurring materials include ammonia borane, sodium borohydride, and various metal nanoparticles such as cobalt, nickel, and ruthenium, often supported on carbon, oxides, or metal-organic frameworks. The primary objective is to enhance the rate and efficiency of hydrogen evolution for storage and fuel applications. Methods frequently involve the synthesis of supported nanoparticles, bimetallic systems, and heterostructures to optimize catalytic activity. The research consistently targets the improvement of hydrogen generation kinetics and the stability of the catalytic process in liquid-phase environments.
The largest share of the community's output is found in hydrogen research, accounting for 60% of all hydrogen research tracked, with 3,319 papers in this group. Boron research also shows a significant presence, representing 50% of all boron research with 754 papers.
The community comprises 5,142 papers, publishing most frequently in the International Journal of Hydrogen Energy, the Journal of the American Chemical Society, and the Journal of Power Sources.
Recent work continues to explore novel catalyst structures, including high-entropy oxides, metal-organic frameworks, and heterostructures, to improve the efficiency of hydrogen generation from ammonia borane and sodium borohydride hydrolysis.
