TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preparation (Claimed): Preparation of (I) comprises depositing metal-containing corrin compound onto a conductive support. Preferred Process: The process comprises chemisorbing the metal-containing corrin compound onto the conductive support from a solution comprising at least one organic or polymeric compound. The process further comprises mixing at least one metal with the metal-containing corrin compound prior to deposition onto the conductive support. Preferred Components: (I) further comprises at least one conductive support, where the metal-containing corrin compound is deposited on at least one conductive support. The conductive support comprises surface functional groups, where the metal-containing corrin compound is covalently attached to the conductive support using a coupling agent bonded to the surface functional groups. The conductive support is a metal-based compound or a carbon-based compound. (I) further comprises at least one metal, where the metal-containing corrin compound is mixed with the metal. The metal is gold, silver, copper, platinum, palladium, ruthenium, rhodium, iron, cobalt or nickel. The metal-containing corrin compound comprises a metal comprising Group 2 metals or transition metals comprising Groups 5-12 of the periodic table. The metal-containing corrin compound comprises a metal comprising iron, cobalt or nickel. The transition metal is a reduced type metal or an oxidized type metal. The metal-containing corrin compound comprises a metal complex derived from at least one organic or polymeric compound. The metal-containing corrin compound is chemisorbed from a solution of the organic or polymeric compound onto the conductive support. The metal-containing corrin compound has the structure of formula (3a)-(3d). The metal-containing corrin compound is derived from cyanocobalamin of formula (2a).Ring A = corrin ring;M = Group 2 metal or transition metal;R = CN, OH or CxHyOzNm; andx-z, m = 0 or an integer. EXAMPLE - Vitamin B12 was heated at 600-900 degrees C in an inert atmosphere to remove the hydrophilic groups and yield a catalyst. The obtained catalyst and Vulcan XC-72R (RTM: Carbon black) were strongly stirred in a water solution to yield a B12/carbon black (CB) suspension. The suspension was subsequently filtered using filter paper to produce B12/CB slurry in which the B12 was adsorbed onto the carbon black. The B12/CB slurry was then pyrolyzed in a nitrogen atmosphere at 600 degrees C. The B12 was then bonded to the carbon black via chemical bonds rather than adsorption, thus B12 deposited on a conductive support.
