NOVELTY - A high-carbon monoxide-toxicity-resistant platinum-M/graphene catalyst preparation method involves dissolving chloroplatinic acid hexahydrate and M compound in alcohol solvent. Non-ion active phosphoric acid or citric acid is added to the mixture and heated at 20-65 degrees C for 15-30 minutes. Graphite alkene is dipped in a platinum-M active precursor. De-ionized water and reducing agent are added, filtered and washed. Microwave dehydration is carried out to obtain composite catalyst, where M is palladium, gold, ruthenium, molybdenum, nickel, cobalt, iron and tin. USE - Method for preparing high-carbon monoxide-toxicity-resistant platinum-M/graphene catalyst. ADVANTAGE - The method enables preparing high-carbon monoxide-toxicity-resistant platinum-M/graphene catalyst with low platinum loading, improved anti-carbon monomer poisoning ability and improved catalytic activity, in a simple and efficient manner.
