Abstract Single-atom catalysts (SACs) offer efficient metal utilization and distinct reactivity compared to supported nanoparticles. Structure-function relationships for SACs often assume that active sites have uniform coordination environments at particular binding on support surfaces. Here, we investigate the distribution of Pt SAs dispersed shape-controlled anatase TiO 2 supports specifically exposing (001) (101) are found surface, consistent with existing structural models, whereas those beneath surface after calcination. under surfaces exhibit lower CO oxidation than due their limited accessibility gas phase species. deposited commercial-TiO both in bulk, posing challenges structure-function relationship development. This study highlights heterogeneity SA oxide supports, emphasizing a previously overlooked consideration design SACs.
