Abstract

Ag-based nanocrystals have emerged as an important candidate for CO₂ reduction reaction (CO₂ RR) owing to the increasing amount of CO₂ in the atmosphere, which has shown a propensity to alleviate environmental problems and produce high value-added chemicals. This paper reviews the surface and interface engineering of Ag-based catalysts towards CO₂ RR, which involve in the morphology control, composition manipulation, and support effects. Various synthesis approaches are presented to discuss their influence on the size, crystal structure and morphology of Ag-based catalysts, including pure Ag NPs, Ag-based alloys, Ag/metal oxides composites as well as Ag/carbon materials. Next, the development of Ag-based surface and interface engineering that is essential to accelerate the formation of CO and its further conversion to C1 or even multicarbon products is systematically discussed. Finally, we give a short conclusion, and perspectives on the rational design of Ag-based catalysts based on surface and interface engineering will be discussed.

Keywords: Ag; CO2RR; alloys; electrocatalysis; surface and interface engineering.
