EXAMPLE - A slurry was prepared using CDX-975 (RTM: carbon black) (100 g), glacial acetic acid (in ml) (25) and deionized water (750). Aniline (20 g) was added to the obtained slurry along with continuous stirring. The solution containing ammonium persulfate (45 g) in deionized water (250), was added to the carbon black slurry, and stirred continuously at room temperature for 2 hours. The obtained slurry was filtered, washed with deionized water, dried at 110degreesC for 4 hours, and pulverized to obtain carbon powder containing grafted polyaniline conductive polymer. The carbon powder had electronic conductivity of 3.7 S/cm measured according to ASTM D257. Carbon black had mean particle size of 21 nm measured according to ASTM D3849, specific surface area of 242 m2/g measured by nitrogen adsorption method according to ASTM D4820, STSA specific surface area of 130 m2/g measured according to ASTM D5816, dibutyl phthalate (DBP) oil absorption of 170 ml/100 g, volatility of 1%, blackness index of 112 and tint strength of 87 measured according to ASTM D3265. A supported catalyst containing platinum with grafted polyaniline on carbon surface, was prepared using polyaniline grafted carbon black, deionized water, 1% chloroplatinic acid solution, 1M sodium bicarbonate solution and 3% formaldehyde solution.
