Polyol Synthesis of Bimetallic FePt Nanoparticles over h-BN Substrate

Year: 2024

Type: article

Abstract: Hexagonal boron nitride (h-BN) is a promising support for the deposition of functional metallic nanoparticles for next generation of catalysts. Multicomponent metallic NPs, such as bimetallic FePt NPs, are attracting much attention as catalytically active sites because their properties can be superior to their single-element counterpart. To achieve the best catalytic properties, careful control of the chemical composition of the bimetallic NPs on the surface of h-BN substrates is necessary. Herein we report the development of a polyol synthesis protocol that elucidates the relationship between the initial and resulting Fe:Pt molar ratio in a FePt/h-BN material. TEM, STEM, EDXS, BET and BJH methods were utilized to characterize the surface and structure of the h-BN support and FePt/h-BN heterostructures.
