Circumventing the scaling relationship on bimetallic monolayer electrocatalysts for selective CO₂ reduction.

ABSTRACT: Electrochemical conversion of CO₂ into value-added chemicals continues to draw interest in renewable energy applications. Although many metal catalysts are active in the CO₂ reduction reaction (CO₂RR), their reactivity and selectivity are nonetheless hindered by the competing hydrogen evolution reaction (HER). The competition of the HER and CO₂RR stems from the energy scaling relationship between their reaction intermediates. Herein, we predict that bimetallic monolayer electrocatalysts (BMEs) - a monolayer of transition metals on top of extended metal substrates - could produce dual-functional active sites that circumvent the scaling relationship between the adsorption energies of HER and CO₂RR intermediates. The antibonding interacti
