Abstract

The present invention relates to a method for preparation of a catalyst for use in production of elongate microstructures and/or nanostructures substantially comprising Boron nitride (BN), the method includes reacting a first substance selected from oxides or nitrates of Na, K or Li; with a second substance selected from Fe2O3, Al2O3, SiO, Fe(NO3)3, Al(NO3)3, and SiH4(NO3)4; such that if the first substance is an oxide, the second substance is selected from the list consisting of Fe2O3, Al2O3 or SiO; and if the first substance is a nitrate, the second substance is selected from Fe(NO3)3, Al(NO3)3, and SiH4(NO3)4; wherein the molar amount of the second substance is at least twice of the molar amount of the first substance. The present invention further proposes a method for production of elongate microstructures and/or nanostructures substantially comprising BN, and an entity which is obtainable through such method.
