1. A preparation method of a nitrogen-doped peony-shaped molybdenum oxide, comprising the following steps of:
(1) adding a regulator into a molybdenum-containing solution for reaction, concentrating and thermal treatment to obtain a peony-shaped molybdenum oxide; and
(2) dissolving the peony-shaped molybdenum oxide in a conditioning agent, and adding an amine source for standing, centrifuging, washing and heat treatment, thus obtaining the nitrogen-doped peony-shaped molybdenum oxide; wherein, the regulator is at least one of nitric acid, ammonium nitrate, sodium persulfate, ammonium persulfate, concentrated sulfuric acid, H2O2, ozone or sodium hypochlorite;
wherein in step (2), the conditioning agent is at least one of sodium acetate, ammonium acetate, sodium formate, diaminoethane, sodium oxalate, ammonium benzoate, sodium phenylacetate, sodium propionate, sodium tartrate, sodium citrate or ammonium citrate; and
wherein in step (2), the amine source is at least one of aniline, dimethylamine, trimethylamine, benzylamine, phenethylamine, ethamine, diethylamine, propylamine, phenylene diamine, benzylamine, benzene dimethylamine or benzedrinum.
