Metal‐Free Catalysis of Ammonia–Borane Dehydrogenation/Regeneration for a Highly Efficient and Facilely Recyclable Hydrogen‐Storage Material

As easy as ABC: Mesoporous graphitic carbon nitride (MGCN; g-C3N4) is utilized to support ammonia borane (AB) on the basis of its accessible nanoporous structure and basic properties. A high loading of uniformly dispersed AB nanoparticles into the MGCN is possible giving greatly enhanced H2 generation from AB, and facile regeneration cycles by a hydrazine hydrogenation process, even at room temperature.
