Hydrogen forms chemical compounds with most other elements and a variety of different bonds. This fascinating chemistry hydrogen has continuously provided new materials composites prospects for rational design the tailoring properties. review highlights range boron nitrogen based hydrides illustrates how release uptake properties can be improved.
Mechanochemical synthesis using CeCl3-MBH4 (M = Li, Na or K) mixtures are investigated and produced a new compound, LiCe(BH4)3Cl, which crystallizes in cubic space group I4̅3m, 11.7204(2) Å. The structure contains isolated tetranuclear anionic clusters [Ce4Cl4(BH4)12]4– with distorted cubane Ce4Cl4 core, charge-balanced by Li+ cations. Each Ce atom coordinates three chloride ions borohydride groups via the η3–BH3 faces, thus completing coordination environment to an octahedron. Combination...

Abstract Intense literature and research efforts have focussed on the exploration of complex hydrides for energy storage applications over past decades. A focus was dedicated to determination their thermodynamic hydrogen properties, due high gravimetric volumetric capacities, but application has been limited because harsh working conditions reversible release uptake. The present review aims at appraising recent advances different hydride systems, coming from proficient collaborative...
Abstract The development of efficient storage systems is one the keys to success energy transition. There are many ways store energy, but among them, electrochemical particularly valuable because it can electrons produced by renewable energies with a very good efficiency. However, solutions currently available on market remain unsuitable in terms capacity, recharging kinetics, durability, and cost. Technological breakthroughs therefore expected meet growing need for storage. Within framework...
