| titleOfInvention | Efficient electrocatalyst for oxygen reduction reaction in acid-base solution and preparation method thereof |
| abstract | The invention discloses a high-efficiency electrocatalyst suitable for oxygen reduction reaction in acid and alkaline electrolyte solutions and a preparation method thereof. The main content of the invention comprises (1) preparing a polyaniline-loaded NiCo catalyst precursor (NiCo @ PANI) in the presence of nickel cobalt salt; (2) uniformly mixing a catalyst precursor (NiCo @ PANI), a multi-wall Carbon Nano Tube (CNT) and dicyandiamide (DCD) in different proportions, and then carrying out N 2 Heating at 800 ℃ in the atmosphere to obtain a nickel-cobalt-doped C-N composite material (NiCo @ C-N); (3) then taking the NiCo @ C-N composite material as a carrier and utilizing KMnO 4 And MnCl 2 Manganese dioxide (MnO) produced by the reaction 2 ) Preparing MnO 2 -NiCo @ C-N composite catalyst. MnO of the present invention 2 The NiCo @ C-N catalyst has extremely high electrocatalytic activity on oxygen reduction reaction in acidic and alkaline solutions; the catalyst of the present invention is mainly composed of non-platinum metal (nickel-cobalt) and carbon-nitrogen, the cost of the catalyst is greatly reduced, the electrocatalytic activity is strong, and the catalyst has wide application prospects in fuel cells and metal-air cells. |
