Description
Summary:This paper describes a simple synthetic route for the synthesis of hexagonal boron nitride ( h -BN) powders with high specific surface area, in which BBr 3 , NH 4 Cl and Al powders are used as starting materials. The structure and composition of the powders were characterized by electron diffraction, Fourier transformation infrared spectroscopy and X-ray photoelectron spectroscopy in the selected area. X-ray diffraction shows wide peaks of crystalline h -BN with the particle size on the nanometer scale, and transmission electron microscopy reveals that the products have a novel spongy morphology. Silver nanoparticles loaded h -BN sponges were prepared via a one-step synthesis method. Different reaction conditions for the formation of h -BN sponges were also investigated.
