TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Composition: The transition metal is chosen from titanium, vanadium, chromium, manganese, iron, cobalt, nickel, copper, zirconium, molybdenum, ruthenium, rhodium, palladium and lanthanoid. The hydride complex is chosen from sodium borohydride, lithium borohydride, sodium cyanoborohydride, zinc borohydride and sodium acetoxyborohydride. The porous material is a zeolite. The zeolite is a zeolite which carries out ammonium-ion (NH4+) exchange.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Property: The relative pressure of the carbonaceous material which shows maximum value of inclination of the water vapor adsorption isotherm is 0.6 or less. Preferred Process: The manufacture of microporous carbonaceous material further includes impregnating porous material in transition-metal salt solution, forming liquid mixture, separating microporous carbonaceous material by stirring liquid mixture under reduced pressure, centrifuging such that transition metallic is absorbed to the carbonaceous material, mixing carbonaceous material containing transition metal with reducing agent solution, carrying out liquid phase reduction, depositing transition metal on surface of micropores, washing the microporous carbonaceous material using pure water and drying. Preferred Composition: The content of the nitrogen of the pyridine-type aromatic ring is 10% or more. A transition metal is supported on the surface of the micropores. The nitrogen containing organic compound is cyano-group and amino-group substituted hydrocarbon, 5-membered nitrogen-containing heterocyclic-type compound, or 6-membered nitrogen-containing heterocyclic type compound preferably ethylene or propylene derivative having amino groups and cyano groups, optionally substituted imidazole, oxazole, pyrazole, triazole, pyridazine, pyrimidine, pyrazine, triazine and tetrazine compound. The reducing agent solution contains hydride complex. The solvent in the transition-metal salt solution and/or the reducing agent solution is primary alcohol or ether.
