Boron-based materials have been widely studied for hydrogen storage applications. Examples of these compounds are borohydrides and boranes. However, all of these present some disadvantages that have hindered their potential application as hydrogen storage materials in the solid-state. Thus, different strategies have been developed to improve the dehydrogenation properties of these materials. The purpose of this review is to provide an overview of recent advances (for the period 2015–2021) in the destabilization strategies that have been considered for selected boron-based compounds. With this aim, we selected seven of the most investigated boron-based compounds for hydrogen storage applications: lithium borohydride, sodium borohydride, magnesium borohydride, calcium borohydride, ammonia borane, hydrazine borane and hydrazine bisborane. The destabilization strategies include the use of additives, the chemical modification and the nanosizing of these compounds. These approaches were analyzed for each one of the selected boron-based compounds and these are discussed in the present review.

A constellation of technologies have been researched with an eye towards enabling a hydrogen economy. Within the research fields of hydrogen production, storage, and utilization in fuel cells, various classes of materials have been developed targeting higher efficiencies and utility. This Review examines recent progress in these research fields from the years 2011-2021, exploring the concepts and materials directions important to each. Particular attention has been given to catalyst materials enabling the green production of hydrogen from water, chemical and physical storage systems, and materials used in technical capacities within fuel cells. Quantification of publication and materials trends provides a picture of the current state of development within each node of the hydrogen economy.

Aqueous-phase reforming of organic molecules to hydrogen is a promising strategy to address the production and storage of sustainable hydrogen with lower costs; however, the synthesis of inexpensive transition metal (TM) catalysts with desirable activity and stability for the reaction is still challenging. In this work, a green and efficient approach for modulating the geometric/electronic structure of metal/hydrochar nanocomposites from sustainable biomass was proposed for enhancing H 2 production via aqueous-phase reforming of methanol (APRM). A Ni/HC nanocomposite with a special thistle (a perennial species of flowering plant)-like three-dimensional (3D) architecture was first constructed as a model catalyst to expatiate the critical role of modulating an ordered mesoporous structure and interface electron transfer for enhancing APRM. Deliberately balancing heteroatom doping and soft templates contribute to the successful fabrication of the thistle-like superstructure, and such hierarchically porous architectures demonstrated efficient catalysis for APRM, owing to their unique properties, including a highly uniform morphology, narrow particle size distribution, and mesoporous texture with excellent accessibility. In addition, the experimental investigation and density functional theory calculations both substantiated that the combination of heteroatom doping and soft templates was beneficial for the strong electronic metal−support interaction (EMSI) of the metal/hydrochar nanocomposite, which leads to enhanced methanol adsorption, activation, and subsequently improved APRM performance. The electronic structure of the metal/hydrochar nanocomposite played a more significant effect on the intrinsic APRM activity than the geometric structure like the formation of the thistle-like superstructure. Benefiting from the tailored electronic and geometric structure, the resulting Ni 0.1 /HC-N 1.5 -S 1 catalyst exhibited an unprecedented average turnover frequency (TOF) of 89.5 mol H2 / mol Ni /min, higher than any other known platinum group metal-free catalysts, approaching the reactivity of the state-of-the-art noble metal-based APRM catalysts, while showing excellent stability over 10 consecutive reaction cycles.
