NOVELTY - Anti-reverse electrode catalyst comprises precious metal platinum as main active element, iron, cobalt, nickel, copper, tin, bismuth, manganese, tungsten, molybdenum, yttrium, gold, palladium, rhodium, ruthenium and/or iridium as control components, and porous nano-conductive materials as carrier supported platinum-based catalyst. USE - The anti-reverse electrode catalyst is used for fuel cell and metal air battery or various film type electrolytic cell. ADVANTAGE - The catalyst has very excellent catalytic activity, stability, anti-toxicity and anti-reverse polarity ability, and has low platinum content, high utilization rate and low total cost. The preparation method is stable and reliable; the expansion is convenient and the cost is low. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing the catalyst by adopting a multistep reduction and chemical replacement method, which involves (i) performing heat treatment of porous titanium nitride, carbon black, carbon nanotubes, and/or graphene in an inert or reducing atmosphere at 100-2000degrees Celsius at a heating rate of 0.5-20degrees Celsius/minute for 0.1-10 hours, naturally cooling, replacing nitrogen and sealing, where the inert gas comprises nitrogen, ammonia, methane, hydrogen, and/or argon, (ii) dispersing the carrier material in a weakly reducing solution by ultrasonic dispersion, ball-milling, stirring or cutting, (iii) adding metal salt precursors of iron, cobalt, nickel, copper, tin, bismuth, manganese, tungsten, molybdenum, yttrium, gold, palladium, rhodium, platinum, ruthenium and/or iridium to the solution of step (ii), adding surfactant, structure directing agent and/or reducing agent, and adjusting the pH of the solution to 9-13 using an alkaline solution, (iv) heating and reducing the solution in a reactor or a tubular reactor, where the added metal salt precursor is completely reduced, reacting at 40-400degrees Celsius for 1-24 hours, and heat-preserving until stirring is maintained, (v) dripping platinum salt precursor solution to the solution in step (iv), continuously reacting for 1-24 hours, adding a small amount of metal salt precursors of gold, ruthenium and/or iridium, reacting for 1-3 hours, completely reacting the solution in the reactor or the tubular reactor, filtering, washing, and drying, and (vi) subjecting the catalyst obtained in step (v) to high temperature treatment at 100-1200degrees Celsius.
