Abstract

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.
