Concurrent activation of CO2 and H2O on sulfur-doped CNT-supported nickel phthalocyanine for electrochemical CO2 reduction to CO

Concurrent activation of CO2 and H2O is essential for CO2 electroreduction reaction, but challenging. A sulfur-doped carbon nanotubes-supported nickel phthalocyanine (NiPc/S-CNTs) can concurrently activate CO2 and H2O, promoting CO2 protonation to *COOH. The NiPc/S-CNTs achieves CO Faraday efficienc...

Description
Summary:Concurrent activation of CO2 and H2O is essential for CO2 electroreduction reaction, but challenging. A sulfur-doped carbon nanotubes-supported nickel phthalocyanine (NiPc/S-CNTs) can concurrently activate CO2 and H2O, promoting CO2 protonation to *COOH. The NiPc/S-CNTs achieves CO Faraday efficiency of >96% at current density from −20 to −140 mA cm−2.
