Abstract

The invention provides a carbon material with a catalytic performance on ORR (Oxygen Reduction Reaction) as well as a preparation method and application of the carbon material. The preparation method comprises the following steps: washing chrysanthemum flowers and drying; weighing the chrysanthemum flowers and distilled water and adding into a reaction kettle provided with a polytetrafluoroethylene liner; reacting at 150DEG C to 220 DEG C for 16h to 48h; after reacting, cooling to room temperature and carrying out solid-liquid separation on an obtained brownish black product; carrying out activation treatment on a collected black solid with zinc chloride at the room temperature; then putting the black solid into a tubular furnace and carbonizing at 700 DEG C to 900 DEG under an inert atmosphere for 1h to 4h; washing and drying to obtain the carbon-doped carbon material with the catalytic performance on the ORR. The carbon material provided by the invention has the excellent catalytic performance on the ORR and excellent lasting stability; a preparation process is simple, raw materials re easy to obtain and the cost is low.

Description

technical field

[0001] The invention belongs to the fields of carbon nanometer material preparation and fuel cells, and in particular relates to a method for preparing a carbon material with excellent catalytic performance for oxygen reduction reaction by one-step reaction. Background technique

[0002] A fuel cell is a device that directly converts the chemical energy of fuel into electrical energy. The products of its chemical reaction are mainly water and carbon dioxide. The process does not go through the combustion step, and its energy conversion is not limited by the Carnot cycle. Therefore, the energy conversion of fuel The efficiency is relatively high. With the development of society, the demand for energy is increasing. As a new technology that uses energy efficiently and is environmentally friendly, fuel cells enjoy the reputation of "Energy Star in the 21st Century" and are considered to be efficient, high-energy, and pollution-free power supply devices that can...
