Abstract
A method to release hydrogen from a material comprising hydrogen fixed fullerenes involves irradiating the hydrogen fixed fullerenes with electromagnetic radiation of sufficient intensity to release hydrogen rapidly upon irradiation. The intensity of the irradiation and/or the area of irradiation can be adjusted to control the rate and extent of hydrogen release. The hydrogen depleted material comprising hydrogen fixed fullerene can be hydrogenated to regenerate the material.
