Protocol for fabrication and evaluation of oxide-modified Cu foils as heterostructured electrodes for electrochemical CO2 reduction

Abstract

Summary: Heterostructured catalysts based on Cu and oxides are promising for the efficient conversion of CO2 to multi-carbon products. In this protocol, we describe the fabrication and characterization of Cu/oxide heterostructured catalysts and the evaluation approach of electrochemical CO2 reduction reaction (CO2RR) performance in an H-type cell. We also provide the details of in situ surface-enhanced Raman measurement and theoretical calculations. The protocol can be useful for constructing self-supported electrodes and assessing the CO2RR performance of as-fabricated electrodes.For complete details on the use and execution of this protocol, please refer to Li et al. (2022). : Publisher’s note: Undertaking any experimental protocol requires adherence to local institutional guidelines for laboratory safety and ethics.
