METHOD FOR PREPARING ELECTROCATALYST FOR SELECTIVE REDUCTION OF CARBON DIOXIDE

摘要

The present invention relates to a method for preparing an electrocatalyst for selective reduction of carbon dioxide, comprising the steps of: (A) dissolving a metal precursor in an organic solvent and then performing the metal precursor with a first heat treatment to prepare a metal precursor solution; (B) dispersing a carbon support in a mixed solution of a fixing agent and the organic solvent by ultrasonic waves to prepare a carbon support solution; (C) adding the carbon support solution into the metal precursor solution and performing a second heat treatment for 1 to 3 hours, thereby improving the Faraday efficiency and showing lower over-potential in the selective reduction from CO_2 to CO.;COPYRIGHT KIPO 2017
