Stepwise assembly of thiacalix[4]arene-protected Ag/Ti bimetallic nanoclusters: accurate identification of catalytic Ag sites in CO₂ electroreduction.

ABSTRACT: The accurate identification of catalytic sites in heterogeneous catalysts poses a significant challenge due to the intricate nature of controlling interfacial chemistry at the molecular level. In this study, we introduce a novel strategy to address this issue by utilizing a thiacalix[4]arene (TC4A)-protected Ti-oxo core as a template for loading Ag¹⁺ ions, leading to the successful synthesis of a unique Ag/Ti bimetallic nanocluster denoted as Ti₈Ag₈. This nanocluster exhibits multiple surface-exposed Ag sites and possesses a distinctive "core-shell" structure, consisting of a {Ti₄@Ag₈(TC4A)₄} core housing a {Ti₂O₂@Ag₄(TC4A)₂} motif and two {Ti@Ag₂(TC4A)} motifs.
