| titleOfInvention | Composite material and preparation method and application thereof |
| abstract | The application discloses a composite material, a preparation method and application thereof, wherein the composite material comprises multi-wall carbon nano tubes, metal and defective oxides; the metal and the defective oxide are loaded on the outer wall of the multi-wall carbon nano tube; the metal comprises platinum; the defective oxide is selected from at least one of zirconium dioxide, titanium dioxide and silicon dioxide. The composite material provided by the invention can improve the catalytic activity of platinum and prolong the service life of the platinum. The mass activity of the catalyst for oxygen reduction is more than 4.1 times that of a Pt/C catalyst of Johnson Matthey company. After 5 ten thousand cycles in 0.1M perchloric acid solution saturated with oxygen, the mass activity is only reduced by 1.7%; while the commercial Pt/C decreased by 43.7%. |
