Constructing SiO₂-Supported Atomically Dispersed Platinum Catalysts with Single-Atom and Atomic Cluster Dual Sites to Tame Hydrogenation Performance.

ABSTRACT: Construction and optimization of stable atomically dispersed metal sites on SiO₂ surfaces are important yet challenging topics. In this work, we developed the amino group-assisted atomic layer deposition strategy to deposit the atomically dispersed Pt on SiO₂ support for the first time, in which the particle size and ratio of Pt entities from single atom (Pt₁) to atomic cluster (Pt _n ) and nanoparticle (Pt _p ) on the SiO₂ surface were well modulated. We demonstrated the importance of dual-site synergy for optimizing the activity of single-atom catalysts. The Pt_1+n /SiO₂-N catalysts with the coexistence of Pt₁ and Pt _n showed excellent activity and optimi
