Control over Electrochemical CO₂ Reduction Selectivity by Coordination Engineering of Tin Single-Atom Catalysts.

ABSTRACT: Carbon-based single-atom catalysts (SACs) with well-defined and homogeneously dispersed metal-N₄ moieties provide a great opportunity for CO₂ reduction. However, controlling the binding strength of various reactive intermediates on catalyst surface is necessary to enhance the selectivity to a desired product, and it is still a challenge. In this work, the authors prepared Sn SACs consisting of atomically dispersed SnN₃ O₁ active sites supported on N-rich carbon matrix (Sn-NOC) for efficient electrochemical CO₂ reduction. Contrary to the classic Sn-N₄ configuration which gives HCOOH and H₂ as the predominant products, Sn-NOC with asymmetric atomic interface of SnN₃ O₁ gives CO as the exclusive
