Abstract:
A method for introducing hydrogen into layered nanostructures, which method comprises:(a) treating said layered nanostructures with a flowing inert gas at a temperature from about 800.degree. C. to about 1200.degree. C. for an effective amount of time to remove substantially all contaminants wherein the layered nanostructures are characterized as having: (i) at least some regions of crystallinity, (ii) interstices within said crystalline regions which interstices are from about 0.335 nm to 0.67 nm, and (iii) surfaces of said nanostructures which define said interstices, which surfaces have sorption properties with respect to hydrogen; and(b) subjecting the treated layered nanostructures to flowing hydrogen at pressures from about 1,000 psig to about 3,000 psig for an effective amount of time to absorb hydrogen into said layered nanostructures.
