Hydrothermal synthesis of selenium and tellurium nanorods

Abstract

Selenium and tellurium nanorods were synthesised by the reaction of glucose with Na2SeO3 and Na2TeO3 under hydrothermal conditions. The products are characterised in detail by the multiform techniques: X-ray diffraction, energy dispersive X-ray analysis, scanning electron microscopy and transmission electron microscopy. The results show that the selenium products are nanorods with diameters of about 200–300 nm, and lengths ranging between 1 and 3 µm. The diameters of the tellurium nanorods range from 60 to 80 nm and the lengths of several micrometres. The various effects on the growth of nanorods were studied.
