Platinum–copper nanowire networks with enhanced CO tolerance toward methanol oxidation electrocatalysis

NWNs also exhibit an excellent stability with high current densities observed after 3600 s of operation due to the enhanced CO tolerance and the stable three-dimensional (3D) network structure. This work provides a feasible strategy to suppress CO poisoning during the MOR and obtain highly efficient anode catalysts with enhanced durability in the DMFC field.
