Frontispiz: Divergent Activity Shifts of Tin-Based Catalysts for Electrochemical CO2 Reduction: pH-Dependent Behavior of Single-Atom Versus Polyatomic Structures

Abstract

In their Communication (e202418228), Hao Li and co-workers reveal an exciting contrast: the electric field response of the binding strength of *OCHO on Sn-N4-C and polyatomic Sn displays opposite behaviors. This response results in a fascinating, opposite pH-dependent volcano evolution for Sn-N4-C and polyatomic Sn. Most importantly, we propose that distinct strategies are necessary for designing catalysts using single-atom versus polyatomic metal catalysts.
