During the synthesis, pyro-catalytic barium titanate is used as the substrate to reduce the metallic ions dispersed in the solution due to the generated charges at the surface of pyro-materials under temperature oscillation. Chloroauric acid and potassium tetrachloroplatinate are used as precursors to produce gold/platinum bimetallic nanoparticles through a pyro-catalytic process. Transmission electron microscopy characterization, in combination with energy dispersive X-ray spectroscopy mapping, demonstrates that the bimetallic nanoparticle is composed of an Au core and Au/Pt alloy shell structure. Compared to the conventional approaches, the pyroelectric synRSC advancesPyroelectric synthesis of Au/Pt bimetallic nanoparticles-BaTiO₃ hybrid nanomaterials.PMC9054579519731095187310551521004514201050092016YFB0402100Fu BLiu YDeng TSong CWang HWang XShang WWang LTao PfalsePyroelectric synthesis of Au/Pt bimetallic nanoparticles-BaTiO₃ hybrid nanomaterials.This paper introduces an approach to synthesize bimetallic nanoparticles under an alternating temperature field in aqueous solution.
