A facile and totally green approach has been discovered for controlled synthesis of Adams' catalyst (i.e., α‐PtO 2 ) by only using H 2 PtCl 6 and water as reactants; these particles can be easily reduced to Pt nanocrystals (NCs) in ethanol under ambient conditions. The obtained contaminant‐free NCs all exhibit higher activities and stabilities for oxygen reduction reaction (ORR) compared with the state‐of‐art Pt/C catalysts. These PtO 2 and Pt NCs as promising cathode catalysts for fuel cell applications and this simple, straightforward method may open a new way for the synthesis of other “clean” functional nanomaterials.
