Preparation method of carbon catalyst for preparing hydrogen peroxide through electro-catalysis and catalyst

The invention discloses a preparation method of a carbon catalyst for electro-catalysis preparation of hydrogen peroxide and the prepared catalyst, and the preparation method comprises the following steps: mixing phthalimide or phthalonitrile with phosphorus pentoxide and a conductive carbon additive according to a mass ratio of 1: (8-14): (0.8-1.2) to obtain a reaction mixture; adding the reaction mixture into a container, vacuumizing, and reacting at 350-750 DEG C; after the reaction is finished, washing a product with water to remove phosphorus pentoxide, and then drying to obtain the carbon catalyst for preparing hydrogen peroxide through electro-catalysis. According to the catalyst prepared through the method, high-content oxygen heteroatom active sites are introduced, meanwhile, high conductivity of the material is guaranteed, and high activity and high selectivity of hydrogen peroxide produced through electro-catalysis of the material are achieved. 本发明公开了一种电催化制备过氧化氢的碳催化剂的制备方法及所制备的催化剂，首先将苯二甲酰胺或苯二腈与五氧化二磷
