Abstract:
According to one embodiment of a CO2 reduction catalyst of the present invention, a conductive material is immersed in an aqueous solution containing a gold source, and a current or a potential is applied, whereby a highly active CO2 reduction catalyst can be formed in a wide range portion on a surface of the conductive material. According to one embodiment of a CO2 reduction catalyst of the present invention, in a CO2 reduction reaction apparatus including a CO2 reduction electrode having the CO2 reduction catalyst, CO2 is reduced.
