Abstract

The invention relates to the field of function materials, and discloses anode oxygen evolution catalyst FeMnCoNiP amorphous alloy and a preparation method thereof. Fe powder, Mn powder, Co powder, Nipowder and P powder serve as a preparation raw material. The preparation method is a mechanical alloying method and comprises the following specific steps that the metal powder and the nonmetal powderare weighed proportionally and loaded into a hard alloy ball milling tank in a vacuum glove box, an appropriate amount of dispersing agent is added, then, the ball milling tank is sealed and taken out, the sealed ball milling tank is installed on a ball mill to be subjected to alloying ball milling, and the powder obtained after multiple hours of ball milling is the anode oxygen evolution catalyst FeMnCoNiP amorphous alloy. The anode oxygen evolution catalyst FeMnCoNiP amorphous alloy prepared through the method has the good electro-catalysis anode oxygen evolution performance, the preparation process needs only one-step synthesis, and the simple and practical effects are achieved.

Description

technical field [0001] The invention relates to the design and preparation technology of an anode oxygen evolution catalytic material for electrolytic water reaction, and belongs to the technical field of catalytic material preparation. Background technique [0002] Energy and the environment are two major issues restricting the development of the world today. The development of safe, efficient and sustainable clean energy is the key to solving energy and environmental problems. h 2 As a clean, non-polluting renewable energy source with high energy density, it is an ideal choice for addressing both energy and environmental issues at the same time. Electrolysis of water is currently the industrial production of H 2 In the electrolysis water system, the cathode and anode of the electrode separate out H at the same time 2 and O 2 . However, the anode oxygen evolution reaction requires a high activation polarization potential, which is the main reason for the high energy c...
