Effect of Catalysts on Hydrothermal Preparation of boron nitride nanostructures
Boron nitride(BN)has excellent thermal conductivity and electrical insulation,which make it a promising thermal interface material for electronic packaging.Conventionally,the BN nanostructures were made from high cost method,e.g.chemical vapor deposition(CVD),which was restricted by the extremely high reaction temperature as well as the expensive instruments.Herein,a facile hydrothermal method was presented,where the catalysts were used to tune the phase and morphologies of the BN products starting from the boron and nitrogen sources.With different catalysts,the phase of the products could be changed from the orthorhombic to cubic BN,and the morphology underwent an evolution from nanorods to nanoflowers.The results are of great significance for the large-scale fabrication of BN nanostructures in a low cost.
