| titleOfInvention | Co3O4/Co2P coaxial heterostructure material and preparation method and application thereof |
| abstract | The invention relates to Co 3 O 4 /Co 2 The P coaxial heterostructure material and the preparation method thereof comprise the following steps: 1) sintering the cobalt hydroxide nanowire in a hydrogen phosphide atmosphere to obtain a cobalt phosphide nanowire; 2) subjecting the cobalt phosphide nanowire to rapid annealing treatment to oxidize the surface layer to obtain Co 3 O 4 /Co 2 P coaxial heterostructure micro supercapacitor electrode materials. The invention has the beneficial effects that: for Co 3 O 4 /Co 2 P coaxial heterostructure, outer layer of Co 3 O 4 Will provide pseudo-capacitance capacity while the Co of the inner layer 2 P has high conductivity; meanwhile, because the electrochemical reaction only occurs on the surface or near surface of the material, Co is in the inner layer under higher reaction potential 2 P cannot directly contact with the adsorption solution ions and does not catalyze water decomposition. Therefore, the coaxial heterostructure keeps higher capacity and cycling stability, also has better electron conductivity, and the multiplying power performance is improved. |
