TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Composition: The catalyst comprises (wt.%): platinum and ruthenium (5-70); and carbon (balance).Preferred Condition: The platinum and ruthenium are present in an atomic ratio of platinum to ruthenium of 1/4 to 4/1.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Component: The solution of organic gel material comprises resorcinol-formaldehyde as organic gel materials; melamine-formaldehyde; catechol-formaldehyde, and water as a solvent. The solution of organic gel contains phloroglucinol-formaldehyde as organic gel materials, and alcohol as the solvent.Preferred Method: After the gel has been formed, water in the gel is displaced by methanol prior to carrying out the supercritical drying process. The solution of organic gel material with the metal salts and base catalyst is adjusted to pH 5-8 by adding basic amine. The aerogel is carbonized at 500-1200degreesC in an inert atmosphere followed by hydrogenation reduction at 200-1000degreesC. EXAMPLE - After dissolving resorcinol (1.67 g) and formaldehyde (2.41 g) in water (29 g), hexachloroplatinate (0.637 g) and ruthenium chloride (0.340 g) in water (20 g) were added. As a catalyst, sodium carbonate (0.033g) was dissolved in water (10 g) and added to the solution. A dilute solution of ethanolamine and water in a volume ratio of 2:3 was added, and the pH was adjusted to 6.5. The resulting solution was sealed and stored at 80degreesC for 7 days, resulting in formation of a gel, followed by aging. The gel was solvent exchanged for methanol twice per day, for at least5 days. The gel was supercritically dried while applying carbon dioxide at 60degreesC and at a pressure of 230=-240 atm, preparing a carbon aerogel containing metals. The aerogel was carbonized at 1000degreesC for 2 hours in a helium atmosphere, followed by hydrogen reduction at 650degreesC for 2 hours producing the aerogel-type platinum-ruthenium-carbon catalyst containing platinum-ruthenium (20 wt.%); and at a platinum-ruthenium molar ratio of 1:1.
