The present disclosure relates to the manufacturing and use of co-doped multi-metallic electrocatalysts for electroreduction of CO or CO2 to produce n-propanol. The co-doped multi-metallic electrocatalyst includes Cu as well as Ag and a secondary dopant, such as Ruthenium (Ru), Rhodium (Rh), Iridium (Ir), Palladium (Pd), Gold (Au) or Platinum (Pt). The co-doped multi-metallic electrocatalyst can be manufactured using a two-stage method where Cu nanoparticles are first doped with Ru and then doped with Ag. The co-doped multi-metallic electrocatalysts facilitate adsorption of CO, C1-C1 coupling, C1-C2 coupling and certain kinetics for the production of propanol by electroreduction with good selectivity at high current densities.
A method of manufacturing a co-doped multi-metallic electrocatalyst for use in electroreduction, the method comprising:

A co-doped multi-metallic electrocatalyst for electroreduction of CO or CO2 to produce n-propanol, comprising copper (Cu) co-doped with silver (Ag) and a secondary dopant selected from Ruthenium (Ru), Rhodium (Rh), Iridium (Ir), Palladium (Pd), Gold (Au) and Platinum (Pt), wherein the co-doped multi-metallic electrocatalyst has a secondary dopant concentration between 0.5 wt % and 10 wt % measured with XPS, a Ag concentration between 1 wt % and 10 wt % measured with XPS, and a secondary dopant to Ag ratio between 1:1 and 1:10 measured with XPS.
