activity become relevant. These species, most likely containing only a few Pt atoms, are formed only at high temperatures (> 200°C) in lean conditions, and are thus essential for CO oxidation (Figure 109). Stabilising these

highly dispersed reduced clusters, or improving the dynamics of single sites on less interacting facets, could be promising approaches to efficiently use the noble metal and maintain high activity.
