Abstract
TiN NbN and TaN nanocrystals have been selectively prepared through a simple solventfree and convenient reaction under autogenic pressure at moderate temperature RAPET process at 350 °C for 12 h reacting transition metal chlorides and sodium azide The nanostructures obtained are characterized by powder Xray diffraction PXRD transmission electron microscopy TEM and scanning electron microscopy SEM A reaction mechanism is suggested based on the experimental results These rapid reactions produce nanocrystals of TiN NbN and TaN with average sizes of approximately 30 28 and 27 nm respectively as calculated from Xray line broadening An octahedral inorganic fullerene was detected among the various structures of the TiNP P George thanks the BarIlan Research authority for a postdoctoral fellowship and also thanks Dr Tova Tamari Dr Judith Grinblat Dr Yuri Koltypin Ms M Shirly and Mr Avi Marciano for their help with TEM HRTEM measurements technical support XRD diffraction patterns and diffuse reflectance spectroscopy respectively
