Single-atom catalysts for CO2 electroreduction with significant activity and selectivity improvements

We propose the great potential of single atom catalysts (SACs) for CO2 electroreduction with high activity and selectivity predictions over a competitive H2 evolution reaction. We find the lack of an atomic ensemble for adsorbate binding and unique electronic structure of the single atom catalysts play an important role.
