Abstract:
1. A method of making an electrocatalyst for electrochemical conversion of carbon dioxide, comprising the steps of: dissolving copper nitrate trihydrate in deionized water to form a salt solution; adding carbon nanotubes to the salt solution to form a suspension; heating the suspension; adding a urea solution to the suspension to form an electrocatalyst in solution, the electrocatalyst comprising copper material supported on the carbon nanotubes; cooling the solution to room temperature; removing the electrocatalyst from the solution by centrifuging the solution to separate the electrocatalyst out of the solution; washing and drying the electrocatalyst at a temperature of about 110° C.; and calcining the washed and dried electrocatalyst at a temperature of about 450° C. for about four hours in an argon gas flow.
