Abstract
The hydrogen storage product comprises one or more reduced-graphene oxide layers functionalized with a boron species and decorated with an alkali or alkaline earth metal. Each layer of the structure further comprises boron-oxygen functional groups comprising oxygen atoms bonded to boron atoms. The hydrogen storage product has a composition suitable for physisorption of hydrogen molecule, and operates to reversibly store hydrogen under operating conditions of low pressure and ambient temperature.
