NOVELTY - Preparing eutectic solvent-based multi-walled carbon nanotube loaded platinum cobalt catalyst comprises: (i) adding mixed solvent into acidified multi-walled carbon nanotube, dispersing, drop-wisely adding cobalt nitrate solution, sodium hydroxide solution and sodium borohydride in sodium hydroxide solution, stirring under oil bath, adding hydrazine hydrate solution, refluxing, centrifuging, washing and vacuum drying to obtain cobalt/multi-walled carbon nanotube composite; and (ii) adding choline chloride/ethylene glycol-deep eutectic solvent into above product, adding chloroplatinic acid.    USE - The multi-walled carbon nanotube loaded platinum cobalt catalyst is useful in direct methanol fuel cell (claimed).    ADVANTAGE - The catalyst increases the dispersion of noble metal and electrochemically active surface area, enhances the catalyst electro-catalytic activity and stability for methanol oxidation and has anti carbon monoxide poisoning ability.    DETAILED DESCRIPTION - Preparing eutectic solvent-based multi-walled carbon nanotube loaded platinum cobalt catalyst comprises: (i) adding 100 ml mixed solvent (ethanol and water in a volume ratio of 1:1) into 100 mg acidified multi-walled carbon nanotube, dispersing ultrasonically for 30 minutes, drop-wisely adding 20 ml of 7.14 mg/ml cobalt nitrate solution under magnetic stirring condition, then drop-wisely adding 10 ml of 0.1 M sodium hydroxide solution and 0.5 mg sodium borohydride in sodium hydroxide solution, stirring at room temperature for 30 minutes, transferring the reaction system into oil bath, continuing to stir, heating to 120 degrees C, then drop-wisely adding 10 ml of 50% hydrazine hydrate solution, stirring by refluxing for 10 hours, purifying the product by centrifugation, washing and vacuum drying to obtain cobalt/multi-walled carbon nanotube composite; and (ii) adding 20 ml choline chloride/ethylene glycol-deep eutectic solvent into 10 mg cobalt/multi-walled carbon nanotube composite, dispersing ultrasonically, drop-wisely adding 100-700 mu l of 19.3 mM chloroplatinic acid of deep eutectic solvent, stirring magnetically for 10 minutes, adding 60 mg sodium borohydride solid, continuing to stir, transferring the suspension into 30 ml reaction kettle, reacting for 120-200 degrees C for 3-15 hours, centrifuging the reaction product, washing and vacuum drying. An INDEPENDENT CLAIM is also included for multi-walled carbon nanotube loaded platinum cobalt catalyst, prepared by above mentioned method.
