Electrochemical determination of hydrazine by using MoS2 nanostructure modified gold electrode

In this paper, MoS2 nanostructure was synthesized by using ammonium molybdate and thiourea as precursors through annealing in a tube furnace. The characterized for morphological, structural elemental composition field emission scanning electron microscope (FESEM), powder X-ray diffraction energy-dispersive spectroscopy (EDS). as-synthesized then immobilized on the gold electrode (working electrode) electrochemical detection of hydrazine. Cyclic voltammogram shows an intense peak at 22 µA, which proved high electrocatalytic ability sensor. strong activity regarding oxidation hydrazine is ascribed to good transfer surface area nanoparticles. Further, chronoamperometric study conducted estimate sensitivity limit sensor exhibited 196 nM 5.71 µA/µM cm2 respectively. Promising results such electrical conductivity, lower have its potential towards
