“…Various hydrogen storage technologies are currently under investigation, including compressed hydrogen, physical adsorbents, metal hydrides, and chemical hydride systems. Ammonia borane (NH 3 ⋅BH 3 , AB) has become a leading indirect hydrogen storage material because of its high hydrogen content (19.6 wt.%), thermal stability, excellent water solubility at room temperature, and non‐toxicity . The hydrogen stored in AB can be released through thermal dehydrogenation and catalytic dehydrogenation according to Eq.…”

“…[2] The hydrogen stored in AB can be released through thermal dehydrogenation and catalytic dehydrogenation according to Eq. (1) and (2). However, the hydrolysis of AB under the action of appropriate catalyst and the formation of 3 equivalent H 2 at room temperature can be easily released for practical application.…”

Cobalt nanoparticles (NPs) supported on reduced graphene oxide sheets have been synthesized via a facile chemical reduction method by adding surfactant PVA and controlling the preparation process. Compared with regular Co NPs and unsupported waxberry‐like Co NPs, the synthesized Co@rGO exhibited waxberry‐like structure and amorphous state, good dispersion, uniform particle size with 25 nm. The waxberry‐like Co@rGO catalyst needed 10.8 min for hydrolytic dehydrogenation of NH3⋅BH3, with an initial turnover frequency (TOF) of 12.14 molH2⋅min–1⋅molCo–1 and the activation energy of 45.49 kJ⋅mol–1. The improved catalytic activity can be ascribed to the special morphology and decreased particle size of Co NPs, as well as the synergistic effect between graphene sheets and Co NPs. The work also includes the kinetic studies on zero‐order with respect to substrate concentration and first‐order reaction with respect to catalyst concentration.

“…The key to its low temperature hydrogen release ability lies in this particular electronic feature of the Lewis‐base/acid‐adduct in which protic and the hydridic hydrogen are located next to each other. Because of the low hydrogen release temperatures and the wide range of dehydrogenation possibilities, the compound has been studied extensively in recent years . Most research in this context has been devoted to the hydrogen release kinetics of AB in different phases .…”

[9][10][11][12][13][14][15][16][17][18][19][20][21][22] The hydrogen release from AB is accompanied by a heat release caused by the formation of strong BÀ N bonds leading to borazine or polymerized BNH x -waste products like polyaminoborane and heavily cross-linked polyborazylene (PB).…”

Although the development and application of a BNHx‐waste recycling process is one of the major prerequisites for the use of ammonia borane as hydrogen source material, most research groups in the field have focused on AB hydrogen release and only few groups have worked on the development of energetically viable recycling schemes. In our work we target the development of a closed recycling process containing three desired steps: superacid break‐up of the BNHx‐waste, catalytic hydrodehalogenation of the generated boron halide, and base‐exchange between Et3NBH3 and ammonia. Catalytic hydrodehalogenation provides a convenient means to generate B−H bonds using molecular hydrogen, avoiding potentially energetically expensive reduction reagents.

Over the past few decades, the design and development of advanced catalysts for efficient energy conversion technologies have undergone extensive study. Black phosphorus (BP) is considered to be one of the most promising catalysts, exhibiting remarkable performance and drawing significant attention, because of its extraordinary physicochemical properties: a unique layered structure, anisotropic structure, tunable direct bandgap, and ultrahigh charge mobility. In this review, the fundamentals of bulk BP, single-and few-layer phosphorene, and BP quantum dots are briefly introduced, along with their crystal structure, optical and electrical properties, stability, and synthetic methods. Furthermore, recent progress toward diverse BP-based materials for photo-and electrocatalysis for renewable energy is summarized, specifically focusing on water splitting, CO 2 conversion, and nitrogen fixation. Finally, the challenges ahead for these BP-based catalysts are also emphasized, alongside and perspectives on their further development as part of the this fast-flourishing renewable energy field.
