Mesoporous desigels are fabricated as nitrides, carbides, borides, and silicides of metals, particularly transition metals, and most particularly early transition metals. The desigels are prepared by forming a gel of a metallic compound, and removing solvent from the gel. In some instances, the thus produced desigel may be further reacted to change its composition, while preserving its mesoporous structure. The materials are particularly suited as electrodes for capacitors, including ultracapacitors, and for batteries.

[ We claim:] [1.] A method of making a mesoporous desigel comprising:providing a solution containing a first compound of a metal;reacting said first compound in said solution so as to produce a gel comprised of a network of a second compound of said metal embedded in a solvent;removing said solvent from the gel while maintaining at least some of the structure of the network of the second compound, whereby a mesoporous desigel of said second compound is produced; andreacting said mesoporous desigel so as to convert at least a portion of said second compound to a third compound of said metal.
