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: An economical, simple, and efficient steam pretreatment-mediated strategy using nitric acid vapor was introduced to adjust the surface chemistry and textural structure of carbon nanotubes, facilitating the uniform deposition of Ru nanoclusters for enhanced hydrogen production from ammonia borane hydrolysis. Ru nanoclusters with high dispersion (1.71 nm in diameter) were formed on functionalized carbon nanotubes, leading to significantly improved catalytic activity in hydrogen generation from ammonia borane hydrolysis. This strategy provides an efficient approach for preparing various carbon-supported metal catalysts with promising catalytic applications.

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: This study predicts for the first time that the hydrogen storage capacity of ammonia borane (AB) can be increased by inserting H2 molecules into its crystal structure. The new phase, AB-(H-2)(3), is stable over a wide pressure range and reduces the metallization pressure of AB. This research provides insights into increasing the storage capacity of hydrogen storage materials under high pressure conditions.

Summary: The study demonstrates that molecular self-assembly of n-dodecylamine borane in anhydrous THF forms core-shell aggregates, with NH2BH3 groups in the core and alkyl chains in the outer layer. However, the compound is unstable in the presence of moisture, hydrolyzing to produce water-soluble borates. Therefore, investigating the behavior and properties of C12AB should be conducted under anhydrous conditions.

Summary: Primary alkylamine borane adducts CxAB are unconventional molecules with dihydrogen bonds, synthesized by Lewis acid-base reaction between complex (CH3)2S·BH3 and primary alkylamines. The melting temperatures of CxAB increase linearly with ln(x) due to stronger intermolecular Van der Waals forces between the alkyl chains, and are higher than those of the amines by 20-40 degrees C due to dihydrogen bonds.

Summary: Porous borocarbonitrides (BCN) were prepared by pyrolysis of the polymer derived from dehydrocoupled ethane 1,2-diamineborane (EDAB) with the presence of F-127. These materials exhibited nanometer-scale interconnected pores and a high specific surface area up to 511 m(2) center dot g(-1). Gas adsorption experiments showed their interesting CO2 uptake, high CO2/N2 selectivity, and good recyclability after multiple adsorption-desorption cycles. A comparison study with non-porous BCN and commercial BN samples revealed the importance of porosity and carbon doping for CO2 capture. This work demonstrated a simple and interesting two-step synthesis approach for microporous BCN adsorbents from EDAB.
