Hydrogen Storage on Carbon-Based Adsorbents and Storage at Ambient Temperature by Hydrogen Spillover

Hydrogen storage is a crucially missing link to a future ohydrogen economy.o 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.
