Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>NbPt₃ intermetallic nanoparticles (NbPt₃ 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 NbPt₃ NPs. These NbPt₃ NPs exhibit higher stability than pure Pt NPs during repeated electrochemical cycles in H₂SO₄. The NbPt₃ 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 NbPt₃ NPs are promising candidates as electrode catalysts in fuel cells.</p> </abstract>
