Abstract

In this report, Pt/NCNFs/Cu-foil, an efficient and stable catalyst, was prepared by the electrospinning method, which could be directly used for electrochemical reduction of CO₂. Formate with 93% Faradaic efficiency and about 46 mA cm⁻² partial current density could be obtained at −0.6 V_RHE; alcohols with approximately 35% Faradaic efficiency and 14 mA cm⁻² partial current density were achieved at −1.0 V_RHE using the same Pt/NCNFs/Cu-foil cathode. Moreover, Pt/NCNFs/Cu-foil could keep high efficiencies for at least 50 h durability tests.
