▎ 摘  要

NOVELTY - Preparing copper-based single atom alloy catalyst of electrocatalytic reduction carbon dioxide comprises (i) heating small molecule organic solvent to 120-150℃, adding transition metal M ion solution, reacting at constant temperature for 8-12 hours, cooling down to room temperature, and adding copper ion precursor solution to obtain the copper/metal mixed salt solution; (ii) adding the copper/metal mixed salt solution to the graphene oxide solution, adding a nitrogen source, ultrasonically mixing, and freeze-drying to obtain a mixed solid powder; and (iii) roasting above-mentioned mixed solid powder and reducing at high temperature under the protection of an inert gas, washing obtained sample, filtering, and vacuum-drying. USE - The method is useful for preparing copper-based single atom alloy catalyst of electrocatalytic reduction carbon dioxide. ADVANTAGE - The method enables to prepare copper-based single atom alloy catalyst, which has high Faraday efficiency, and improved selectivity generating efficiency of carbon monoxide. The method is simple and cost-effective.
