Abstract

Metal–nitrogen-carbon (M–N-C) single-atom catalysts (SACs) have been widely applied in catalyzing electrochemical redox reactions. However, their long-term catalytic stabilities greatly limit their practical applications. This work investigates the dynamic evolution of two model Cu–N–C SACs with different Cu–N coordinations, namely the Cu1/Npyri-C and Cu1/Npyrr-C, in electrochemical CO reduction reaction (CORR), based on a collection of in situ characterizations including in situ attenuated total reflectance surface-enhanced infrared absorption spectroscopy, in situ X-ray absorption spectroscopy, quasi-in situ electron paramagnetic resonance spectroscopy and in situ ultraviolet–visible spectroscopy,…
