Temperature Dependent Synthesis of Inorganic WS2 Nano Rods

Abstract

In this report we report a simplest way to synthesis inorganic Tungsten disulfide (WS2) nanorods. In this research work we used Tungsten trioxide (WO3) to produce tungsten disulfide with hydrogen gas and sulfur gas to synthesis WS2 nanorods at ambient temperature. This synthesis was done by two steps. The first step is oxide reduction and the second step is Sulfuration. And we have analyzed the changes in the nanorod structure when the reaction time is increased and when the temperature is changed at constant gas flow. The synthesized nanorods are analyzed by SEM, EDS and XRD. We report that we have successfully synthesized WS2 nanorods with the dimension of 100 to 300 nm in diameter and few micrometers in length. And we also report the changes in the structural morphology when the temperature was increased. When the temperature was increased to 1000oC the structure become very ranom.
