Key Points

To explore how Ni incorporation influences the stability and degradation of silver-nickel nanoparticle catalysts in CO2 reduction.
Investigated silver-nickel alloy catalysts with varying Ni content.
Analyzed the density of active sites and electron transfer dynamics.
Conducted comparative investigations of catalyst performance over time.
Incorporation of Ni increases the density of active sites.
Enhanced electron transfer rates between active sites and intermediates were observed.
Silver-nickel catalysts exhibited greater stability under electrochemical conditions.

Implication

Comparative investigation reveals how nickel enhances silver catalyst performance for CO2 reduction, implying better efficiency.

Abstract

The Ni incorporation in Ag–Ni alloy catalyst increases the density of active sites and promotes electron transfer between the active sites and reaction intermediates. Furthermore, a comparative investigation of the...
