| titleOfInvention | Nitrogen and phosphorus co-doped cobalt-based carbon fiber multifunctional electrochemical catalyst and preparation method thereof |
| abstract | The invention discloses a nitrogen and phosphorus co-doped cobalt-based carbon fiber multifunctional electrochemical catalyst and a preparation method thereof, relates to electrochemical catalysts and preparation methods thereof, and aims at solving the technical problem of single catalytic activity of an existing nitrogen/transition metal co-doped carbon material. The electrochemical catalyst disclosed by the invention is formed by codoping nitrogen and phosphorus into a cobalt-based carbon fiber; Co:N:P=4x:x:y; x=1-2; y=1-4; and cobalt is loaded on the surface of the carbon fiber. The preparation method comprises the following steps: (1) adding cobalt nitrate, urea and triphenyl phosphine to N,N-dimethyl formamide, stirring the cobalt nitrate, the urea and the triphenyl phosphine until dissolving, adding polyvinyl pyrrolidone, and stirring and dissolving the polyvinyl pyrrolidone to obtain an electrostatic spinning precursor solution; (2) carrying out electrostatic spinning; and (3) sintering the precursor solution, so as to obtain the nitrogen and phosphorus co-doped cobalt-based carbon fiber multifunctional electrochemical catalyst. The catalyst has oxygen reduction catalysis activity and hydrogen evolution catalysis activity, has oxygen reduction catalysis activity under different acid and alkaline conditions, and can be applied to lithium-air cells and fuel cells. |
