Today, the chemistry of hydrides is an actively developing area of inorganic and organometallic chemistry, which is associated with their extensive use as energetic materials and their role in homogeneous and heterogeneous catalysis and in redox processes. In recent decades, there has been a renaissance of hydride materials for energy applications such as batteries and hydrogen storage. Lightweight hydride materials are used for the development of efficient and reliable systems of renewable energy storage, both for stationary and for mobile applications—what is known to be the main challenge for the implementation of “green energy”, and ultimately the transition to a fossil fuel free society. Another important aspect is the participation of metal hydrides as a catalyst or catalytic intermediates in a wide variety of homogeneous and heterogeneous catalytic processes, the most significant of which are hydrogenation, hydroformylation, as well as processes occurring with the activation of E–H bonds (E = H, C, Si, B, P, N, etc.) and catalytic dehydrocoupling. Finally, metal alumo- and borohydrides are play an undeniable role in selective reduction processes in thin organic synthesis and pharmaceutical production.
This Special Issue aims to present recent advances in hydride chemistry, from the development of new synthetic approaches, determination of crystal structure, the study of their properties (electronic, spectroscopic, optic, etc.), and investigation of their reactivity toward small molecules and bond activation to their use in a broad range of fields, including energetic materials, organometallic chemistry, homogeneous and heterogeneous catalysis, etc. Contributions to this issue could be in the form of communications, full research articles, and reviews on topics related to these fields. Scientific productions of both experimental and computational nature are welcome; mechanistic studies that offer new insights into catalytic processes or chemical reactions are particularly welcome.

Title: Boron hydrogen compounds: from hydrogen storage to battery applications
Authors: Hans-Rudolf Hagemann

Abstract: About 25 years ago, Bogdanovic and Schwickardi (B. Bogdanovic, M. Schwickardi: J. Alloys Compd. 1–9, 253 (1997) discovered the catalyzed release of hydrogen from NaAlH4. This discovery stimulated a vast research effort on light hydrides as hydrogen storage materials, in particular boron hydrogen compounds. In the following years, many new metal borohydrides such as Mx(BH4)y and MxM’y(BH4)z were prepared and characterized. However, it appeared that reaction kinetics and reversibility are not very favorable for the pure compounds, and potential catalysts were explored to improve the performance. The discovery of high ionic conductivity in the high temperature phase of LiBH4 opened a new research direction, and very recently a all-solid-state 4V Na battery prototype using a Na4(CB11H12)2(B12H12) solid electrolyte has been demonstrated. In this review, we present the current knowledge of possible reaction pathways involved in the successive hydrogen release reactions from BH4- to B12H122-, as well as a discussion of relevant properties necessary for high ionic conduction materials.
