Abstract

This invention is directed to a method of reversibly storing hydrogen comprising exposing a solid sorbent of metal-doped carbon-based material to a hydrogen atmosphere at a temperature of from about 250 K to about 973 K under ambient or higher pressure. The metal-doped carbon-based material is generally an alkali metal-doped carbon-based material prepared by mixing a carbon material with an alkali metal salt and calcining the mixture under an atmosphere of inert or reductive gas.
