Cross‐Scale Engineering of Single‐Atom Catalysts from Local Planar Coordination to Spatial Architectures

Small, EarlyView.
This Review presents a cross‐scale framework for single‐atom catalysts, spanning in‐plane and out‐of‐plane coordination; primary coordination, secondary‐sphere interactions, through‐space microenvironments and support interfaces; individual sites and macroscopic architectures; and static design and directed dynamic reconstruction.
