ABSTRACT:
A non-oxide, transition metal based ceramic material has the general formula A.sub.y M.sub.2 Z.sub.x, wherein A is a group IA element, M is a transition metal and Z is selected from the group consisting of N, C, B, Si, and combinations thereof, and wherein x.ltoreq.2 and y.ltoreq.6-x. In these materials, the group IA element occupies interstitial sites in the metallic lattice, and may be readily inserted into or released therefrom. The materials may be used as catalysts and as electrodes. Also disclosed herein are methods for the fabrication of the materials.
