1. A method of preparing a thermally stable nanoparticle/graphene/boron nitride (BN) nanocomposite, the method comprising steps of:
ball-milling a mixture comprising a metal salt, graphene, and boron nitride; and
calcinating the mixture, wherein calcinating the mixture comprises heating the mixture in an oven, wherein the temperature of the oven is increased to a temperature in the range of 325 to 375° C. and subsequently held at that temperature for at least 1 hour.
