Abstract:
Hydrogen storage and release catalysts that are large-scale, efficient, and reversible provide a significant challenge for the development of long-term hydrogen energy systems (HES). This review critically examines catalytic approaches to hydrogen storage systems (HSS), including, metal hydrides, metal-organic frameworks (MOFs), covalent organic frameworks (COFs), porous materials, nanostructured catalysts, bimetallic alloys, hybrid composites, and single-atom catalysts (SACs). It evaluates how catalyst composition, structure, and active-site properties influence hydrogen activation, transport, sorption kinetics, cycling stability, and reversibility. Drawing on experimental findings and theoretical approaches, the review compares these relationships across different material classes. This comparative focus extends assessments based on individual materials or catalyst classes by identifying shared design principles and materials specific limitations. Finally, it outlines the main barriers and proposes research directions for developing sustainable, efficient, and reversible hydrogen storage.

Reduction of Alkenes: Catalytic Hydrogenation
Metals like palladium, platinum, and nickel are commonly used in their solid forms — fine powder on an inert surface. As these catalysts remain insoluble in the reaction mixture, they are referred to as heterogeneous catalysts.
The hydrogenation process takes place on the surface of...
Reduction of Alkenes: Asymmetric Catalytic Hydrogenation
The metal catalyst used can be either heterogeneous or homogeneous. When hydrogenation of an alkene generates a chiral center, a pair of enantiomeric products is expected to form. However, an enantiomeric excess of one of the products can be facilitated using an enantioselective reaction or an...

Reduction of Alkynes to cis-Alkenes: Catalytic Hydrogenation
Like alkenes, alkynes can be reduced to alkanes in the presence of transition metal catalysts such as Pt, Pd, or Ni. The reaction involves two sequential syn additions of hydrogen via a cis-alkene intermediate.
