Enhanced reversible hydrogen storage performance of light metal-decorated boron-doped siligene: A DFT study

Highly efficient hydrogen storage of a Sc decorated biphenylene monolayer near ambient temperature: ab initio simulations

“…[37][38][39][40][41][42][43] Similar trends of increasing wt% have been reported for metal decorated carbon nanotubes (SWCNTs), [44][45][46][47] metal decorated on pristine graphene, [48][49][50][51][52] and metal decorated on B/N doped graphene. [53][54][55][56][57] Metal decorated 2D nanomaterials with triple bonds such as Y + graphyne, Li + Holey graphyne, etc. have also been reported to show boosted gravimetric weight percentages.…”

Molecular Modeling of Cu-, Ag-, and Au-Decorated Aluminum Nitride Nanotubes for Hydrogen Storage Application

“…The energy gain per electron is very high, and the chemical energy per mass of hydrogen (39.4 kWh/kg) is 3 times larger than that of other chemical fuels. , However, the practical utilization of hydrogen energy in fuel-cell-powered cars is constrained by the lack of effective storage and secure conveyance options. For both the adsorption and desorption processes, the H 2 molecules should be stored reversibly with a substantial weight percentage capacity and moderate adsorption energy . Interestingly, physical and chemical storage techniques like high-pressure tanks, liquefied hydrogen, solid-state storage, and carbon-based nanostructures, in which the graphene nanostructure is one of a kind, are recognized as promising candidates for hydrogen storage due to their lightweight and large surface/volume ratio, which is required to achieve a high weight percent capacity .…”

“…For both the adsorption and desorption processes, the H 2 molecules should be stored reversibly with a substantial weight percentage capacity and moderate adsorption energy. 16 Interestingly, physical and chemical storage techniques like high-pressure tanks, liquefied hydrogen, solidstate storage, and carbon-based nanostructures, in which the graphene nanostructure is one of a kind, are recognized as promising candidates for hydrogen storage due to their lightweight and large surface/volume ratio, which is required to achieve a high weight percent capacity. 17 Hydrogen can be stored physically as either a gas or a liquid; storage of hydrogen as a gas typically requires high-pressure tanks (350−700 bar [5000−10 000 psi] tank pressure), while its storage as a liquid requires cryogenic temperatures because the boiling point of hydrogen at 1 atm pressure is −252.8 °C.…”
