A conductive mayenite compound powder having a conduction electron density of 10.sup.15 cm.sup.3 or more and a specific surface area of 5 m.sup.2g.sup.1 or more is produced by: (1) a step for forming a precursor powder by subjecting a mixture of a starting material powder and water to a hydrothermal treatment; (2) a step for forming a mayenite compound powder by heating and dehydrating the precursor powder; (3) a step for forming an activated mayenite compound powder by heating the compound powder in an inert gas atmosphere or in a vacuum; and (4) a step for injecting electrons into the mayenite compound through a reduction treatment by mixing the activated mayenite compound powder with a reducing agent.

A one-step process to synthesize narrow band gap TiO.sub.2TiC core-shell particles is described. A mixture of a fuel source, particularly a hydrocarbon, and a titanium precursor is detonated with a source of oxygen in a constant volume reaction vessel to produce TiO.sub.2TiC core-shell particles. This process can synthesize TiO.sub.2TiC core-shell structures with tailored morphology, size, phase, absorption behavior, and other hybrid morphologies with different properties depending on the Ti/C ratio used in the feed.

Provided is a method of producing a catalyst or adsorbent carrier and a catalyst or adsorbent carrier which can enhance a catalyst or adsorbent function, and prevent fall-off of catalyst particles or adsorbent particles. The surface of a metal base material made of aluminum or an aluminum alloy is subjected to an etching process using an etchant containing iron chloride and an oxide to convert the surface to an uneven and rough surface. The uneven and rough surface of the metal base material is subjected to an anodizing process to form a porous coating along the uneven and rough surface. A large number of catalyst or adsorbent particles are thus carried on the surface of the metal base material on which the porous coating is formed along the uneven and rough surface.
