Key Points

This research aims to uncover critical factors affecting nickel-based catalyst performance in CO2 electrolysis.
Identified key performance factors for NiNC in MEA CO2 electrolysis.
Analyzed the impact of nitrogen precursor impregnation on catalyst performance.
Studied the role of carbon support morphology and synthesis methods.
Determined that nitrogen precursor impregnation significantly influences catalyst-layer structure.
Chelating-agent-assisted synthesis was found to enhance catalyst performance.
Identified optimal carbon support morphology for improved electrolysis efficiency.

Implication

Identifies factors that enhance performance in CO2 electrolysis, suggesting paths to improved efficiency.

Abstract

We identify three factors governing NiNC performance in MEA CO 2 electrolysis: nitrogen precursor impregnation, chelating-agent-assisted synthesis, and carbon support morphology, which collectively determine catalyst-layer structure and performance.
