    摘要： The catalytic composition for the electrochemical reduction of carbon dioxide is a metal oxide supported by multi-walled carbon nanotubes. The metal oxide may be nickel oxide (NiO) or tin dioxide (SnO2). The metal oxides form 20 wt % of the catalyst. In order to make the catalysts, a metal oxide precursor is first dissolved in deionized water to form a metal oxide precursor solution. The metal oxide precursor solution is then sonicated and the solution is impregnated in a support material composed of multi-walled carbon nanotubes to form a slurry. The slurry is then sonicated to form a homogeneous solid solution. Solids are removed from the homogeneous solid solution and dried in an oven for about 24 hours at a temperature of about 110° C. Drying is then followed by calcination in a tubular furnace under an argon atmosphere for about three hours at a temperature of 450° C.
