Abstract Oxygen activation plays a crucial role in many important chemical reactions such as oxidation of organic compounds and oxygen reduction. For developing highly active materials for activation, herein, we report an atomically dispersed Pt on WO 3 nanoplates stabilized by situ formed amorphous H 2 4 out‐layer the mechanism activating molecular oxygen. Experimental theoretical studies demonstrate that isolated atoms coordinated with from [WO 6 ] water , consequently leading to optimized surface electronic configuration strong metal–support interaction (SMSI). In exemplified butanone sensing reduction, atomic Pt/WO hybrid exhibits superior activity than those nanoclusters/WO bare well enhanced long‐term durability. This work will provide insight into origin stability materials, thus promoting development efficient durable single atom‐based catalysts.
