Summary: Ammonia borane exhibits excellent hydrogen storage properties, with nanoconfinement in porous metal-organic frameworks shown to enhance its performance. By modifying the linker in the frameworks, the hydrogen release temperature can be lowered and the formation of gaseous byproducts reduced. In situ XRD diffraction and B-11 MAS NMR studies confirm the stability of the porous host and help identify ammonia borane decomposition products.

Summary: Robust multifunctional substrates in heterogeneous catalysts are highly demanded to effectively stabilize active-metal centers and improve catalytic performances. In this study, a porous quasi-metal-organic framework (quasi-NiCo-MOF) is introduced as a smart substrate to spatially confine bimetallic NiCo-phosphide nanoparticles. A controllable thermal transformation strategy is demonstrated for deli-gandation and phosphorization of the parent NiCo-MOF. The resulting P-NiCo-MOF can efficiently activate and dissociate AB and H2O molecules, delivering a high hydrogen generation rate.

Summary: Theoretical chemistry was used to design a system based on ammonia boranes catalyzed by pyrazoles for the production of dihydrogen as clean fuel. The reactivity of ammonia borane and cyclotriborazane with different pyrazole catalysts was investigated. The results suggest a catalytic cycle in which ammonia borane can store and produce dihydrogen and amino borane, and amino borane can trimerize to produce cyclotriborazane that can also generate dihydrogen. This study proposes a progress in using environmentally sustainable (metal free) catalysts to efficiently extract dihydrogen from small B-N bonded molecules.

The formation of CaZrO3 and Ca-Al-O compounds enables over 80% capacity retention over 50 cycles, with rapid reaction kinetics reaching 80% energy storage capacity within 20-30 minutes. The inert nature of the formed compounds prevents sintering and catalyzes the carbonation reaction.

Summary: A composite material of 0.71 LiBH4-0.29 NaBH4 and CMK-3 carbon with nanopores was successfully synthesized, showing improved hydrogen absorption-desorption kinetics. After five cycles, the composite maintained a consistent uptake of about 3.5 wt.% H-2. The enhanced kinetics were attributed to carbon-hydride surface interactions and the heat transfer capability of the carbon support. The nanopore confinement may also contribute to the improved reversibility.
