Preparation method of air cell electrode catalyst

Abstract

The invention provides a preparation method of an air cell electrode catalyst, which comprises the steps of (1) adding carbon powder into isopropanol for mix, stirring to facilitate uniform distribution of the carbon powder; (2) subjecting the mixture to suction filtration, washing with absolute alcohol, and then filtering and drying; (3) adding the dried material into diammineplatinum nitrite and stirring, and then placing the material into a liquid nitrogen environment for cooling; and (4) drying the cooled catalyst in a vacuum environment, and performing hydrogen reduction to obtain a finished catalyst. Compared with the prior art, the catalyst acquired through the preparation method of the air cell electrode catalyst has smaller particle diameter, and better specific activity and stability.

Description

technical field [0001] The invention relates to a preparation method of an air battery electrode catalyst. Background technique [0002] Air battery, as a new type of battery, has been widely concerned at present. In air batteries, it is usually necessary to set catalysts on the electrode surface to improve the efficiency of air batteries. The catalyst particles of existing air batteries are usually relatively large, which limits the improvement of specific activity. Contents of the invention [0003] The technical problem mainly solved by the present invention is that the catalyst particles of the existing air battery are usually relatively large, so that the improvement of the specific activity is limited. [0004] In order to solve the above technical problems, the embodiment of the present invention discloses a method for preparing an electrode catalyst for an air battery, including: [0005] (1) Mix the toner into the isopropanol and stir to make the toner evenly d...
