Electrocatalytic reduction of carbon dioxide inverse perovskite catalysts

Abstract

The application discloses an inverse perovskite catalyst for electrocatalytic reduction of carbon dioxide, and a preparation method of the inverse perovskite catalyst. 3‑x V x The preparation method of the working electrode is as follows: (1) 10 mg of the inverse perovskite catalyst, 5 mg of carbon black, 50 microliters of nafion solution, 500 microliters of ethanol and 450 microliters of deionized water are mixed and placed in a 2 mL closed container, and ultrasonic treatment is continuously carried out for 1 hour; (2) uniform spraying is carried out, and the working electrode is obtained. The inverse perovskite catalyst has rich indium active site support, good electrical conductivity and magnetism, and can be used as a catalyst for electrocatalytic reduction of carbon dioxide into formic acid.
