%X As a critical alternative
step for the synthesis of important chemical feedstocks and complex
carbon-based fuels, the electrochemical transformation of CO2 into CO holds great significance for the chemical industry. Here,
MnO2 nanosheets array supported nickel foam has been synthesized
and adopted as a binder-free catalyst for electrochemical CO2 reduction reaction (CO2RR). The well-distributed nanosheets
of MnO2 impart a much higher density of accessible active
sites for CO2RR, enabling the selective CO2 reduction
to CO with a large current density (14.1 mA cm–2), excellent Faradaic efficiency (71%) and high electrochemical stability
(10 h). This work first demonstrates the great potential of Mn-based
oxides for electrocatalytic transformation of CO2 to valuable
products.
