Abstract
Hydrogen and gaseous hydrocarbons are stored by introducing the gases into a transition metal dichalcogenide having the formula MX.sub.2. M is selected from the group consisting of Mo, W and Ti and X is selected from the group consisting of S and Se. The MX.sub.2 is in the form of platelets affixed to basal planes of adjacent platelets. The basal planes of adjacent platelets are separated by voids. The composition is prepared by intercalating MX.sub.2 powder with lithium, adding water to separate the MX.sub.2 into single layers and then adding acid to adjust the pH to a range where edges and basal planes of the single layers have opposite charges. Preferably a catalyst is added to the MX.sub.2, the catalyst being selected from the group of metals consisting of Pt, Pd, Ni, Co, Fe, Mg, Zr, Cr, Al, Zn, Mn or combinations thereof. The gas can be recovered from the composition by heating to a temperature of 250.degree. C. when the catalyst is used.
