Hydrogen storage on carbon-based adsorbents and storage at ambient temperature by hydrogen spillover

Hydrogen storage is a crucially missing link to a future hydrogen economy. Extensive hydrogen storage studies have been focused on carbon-based adsorbents due to their light weight, high surface area, and tailorable structure. An overview/analysis of the progress on hydrogen storage on various carbon-based adsorbents is given in this review. Particularly, a recent, fast-developing research directionhydrogen storage via spillover on carbons via added catalysts is reviewed separately. A fundamental understanding of the factors that affect both H₂ and spillover hydrogen storage capacities, as well as strategies for improving the storage performance from the viewpoints of both hydrogen storage and materials chemistry, are discussed.
