TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Components: The metal in combination with platinum is selected from Fe, Ru, Co, Rh, Ir, Ni, Pd, Mo, Sn, La, V or Mn. Preferred Method: preparation of catalyst involves complexing the platinum salt or platinum compound (0.1 - 50 wt.%) optionally with metal salts (0.1 - 50 wt.%) by known polymer or optionally treating POLIMER-Pt complex with metal salt, supporting the resultant complex POLIMER-Pt/metallized POLIMER-Pt onto conductive and porous carbonaceous materials; treating the resulting product in the solid state with gaseous hydrogen at 50 - 900degreesC in solution/suspension with chemical reducing agents, heating in an atmosphere of an inert gas at 1000degreesC. The atomic ratio between platinum and iron/ruthenium/rhodium/iridium/nickel/palladium/tin/molybdenum is 99:1 - 1:99. When more than two metals are used in conjunction with the platinum, the atomic ratio of the metals varies in every possible combination.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Compounds: The 4-(1-((phenyl-2,4-disubstituted)-hydrazine)-alkyl)benzene-1,3-diol is of formula (I). The 3,5-disubstituted phenol is of formula (II). The salts are selected from carboxylates, halogens, alcoholates, acetylacetonates, formates, oxalates, malonates, analogous organic salts, carbonate oxides and/or bicarbonates.R1=H, 1-10C hydrocarbon (optionally hydrogenated);R2,R3=electron attractive group selected from H, halo, acyl, ester, carboxylic acid, formil, nitrile, sulfonic acid, aryl, nitro and linear or branched 1-15C alkyl (optionally functionalized with halo or joined to each other to form cycles condensed with phenyl ring);andR4,R5=electro donating group selected from H, OH, ether, amine, aryl and linear or branched 1-15C alkyl.    TECHNOLOGY FOCUS - POLYMERS - Preferred Components: The polymers are of formula (III).y=2 - 120;x=1 - 2;andn=1 - 3. EXAMPLE - To a suspension of polymer (1 g) in water (100 ml) was added hexachloroplatinic acid (H2PtCl6) (0.2 g) dissolved in water (20 ml) and ruthenium trichloride trihydrate (0.31 g) dissolved in water (20 ml). The pH of the resulting mixture was fixed at 9 by adding NaOH (50 ml) 1M and the mixture was vigorously stirred at room temperature for 6 hours. A dark brown product was formed, which was filtered off, washed several times with distilled water and dried under reduced pressure at 70degreesC until constant weight (yield 0.9 g. Pt content = 6 wt.%, Ru content = 7 wt.%). To a suspension of 0.5 g of the previously obtained product in acetone (100 ml) (finely dispersed by sonication for 30 minutes) was added Vulcan XC-72R (5 g) (previously activated and purified by reflux in HNO3 (100 ml) 1N, filtered off, washed with water several times and heated at 800degreesC for 2 hours in a stream of an inert gas). To this suspension vigorously stirred at room temperature for 4 hours and then cooled to 0degreesC was added portion-wise of NaBH4 (1.5 g). The resulting mixture was allowed to reach room temperature for 2 hours. Afterwards, the solid residue was filtered off, washed with water (3x50 ml) and dried under reduced pressure at 70degreesC until constant weight to give platinum-ruthenium anodic catalyst Pt content = 0.55 wt.%; Ru content = 0.66 wt.% (ICP-AES).
