Tall order: Atomically ordered NbPt3 intermetallic nanoparticles (NPs) are synthesized for the first time through a wet-chemistry route. The NbPt3 NPs are stable during repeated electrochemical cycles, have an improved CO-poisoning tolerance, and exhibit enhanced catalytic activity towards fuel oxidation. The improved catalytic performance of the NbPt3 NPs is attributed to the lowering in the d-band center caused by orbital hybridization of the Nb and Pt atoms.
