“…Porous materials are mostly used for the physical adsorption of hydrogen because of their high specific surface area, porosity, fluid permeability, regularity, and uniform pore structure [9,[48][49][50][51]. Materials such as ACs, porous silica, MOFs, COFs, and zeolites have various characteristics such as shape selectivity, adsorption, stability, and durability [5,52,53].…”

With the rapid growth in demand for effective and renewable energy, the hydrogen era has begun. To meet commercial requirements, efficient hydrogen storage techniques are required. So far, four techniques have been suggested for hydrogen storage: compressed storage, hydrogen liquefaction, chemical absorption, and physical adsorption. Currently, high-pressure compressed tanks are used in the industry; however, certain limitations such as high costs, safety concerns, undesirable amounts of occupied space, and low storage capacities are still challenges. Physical hydrogen adsorption is one of the most promising techniques; it uses porous adsorbents, which have material benefits such as low costs, high storage densities, and fast charging–discharging kinetics. During adsorption on material surfaces, hydrogen molecules weakly adsorb at the surface of adsorbents via long-range dispersion forces. The largest challenge in the hydrogen era is the development of progressive materials for efficient hydrogen storage. In designing efficient adsorbents, understanding interfacial interactions between hydrogen molecules and porous material surfaces is important. In this review, we briefly summarize a hydrogen storage technique based on US DOE classifications and examine hydrogen storage targets for feasible commercialization. We also address recent trends in the development of hydrogen storage materials. Lastly, we propose spillover mechanisms for efficient hydrogen storage using solid-state adsorbents.

Coal is not only a type of fuel but also a precious resource with dual value attributes. Coal is usually used for combustion and electricity generation and is also used as a feedstock in the production of fuels, chemicals, and other high value-added products to improve efficiency. Among these products, coal-based activated carbon is an important part of the high value-added and resource utilization of coal. In this paper, the relevant research on coal-based activated carbon in recent decades is reviewed, including raw material selection, preparation process and mechanism, modification methods, application status, and regeneration methods. Finally, the existing problems and future research directions in the field of coal-based activated carbon are proposed, which has great significance for realizing the high valueadded utilization of coal resources.
