Abstract
Provided are processes for preparing a thermodynamically stable PtBialloy nanoparticle. In certain aspects, the process comprises preparing an aqueous mixture, with the aqueous mixture comprising: an inorganic compound comprising SnClan inorganic compound comprising Bi; and HCl. The process further comprises adding PtClto the mixture. The process results in the spontaneous reduction of Bi and Pt. Excess SnClis adsorbed as a ligand at the surface of the PtBialloy nanoparticle, which serves to stabilize the nanoparticle. Another aspect provides a thermodynamically stable PtBinanoparticle. The nanoparticle comprises a core comprising a PtBialloy. The nanoparticle further comprises a shell at least partially encapsulating the core, with the shell comprising stannous chloride. The thermodynamically stable PtBinanoparticle has a negative charge.
