NbPt 3 intermetallic nanoparticles (NbPt 3 NPs) are synthesized for the first time, and their electrocatalytic performance towards fuel oxidation is tested. Chemical reduction of dichloro(1,5‐cyclooctadiene)platinum(II) and niobium(V) pentachloride in dry diglyme with a superhydride, followed by annealing, yields the desired NbPt 3 NPs. These NbPt 3 NPs exhibit higher stability than pure Pt NPs during repeated electrochemical cycles in H 2 SO 4 . The NbPt 3 NPs are less susceptible to CO adsorption compared with Pt NPs and exhibit improved catalytic activity towards the electrooxidation of ethanol and/or formic acid. These NbPt 3 NPs are promising candidates as electrode catalysts in fuel cells.
