      In the present work, binder-free, stable, high-performance and ultrasensitive platform is proposed for the accurate estimation of hydrazine by using a facile synthesized few-layered sulphur-doped graphene (SG)-modified glassy carbon electrode (SG/GCE). This proposed SG/GCE facilitates hydrazine to be catalytically oxidized at low overpotential. The SG was synthesized by a facile microwave-assisted solvothermal route, further examined by electron microscopy, Raman and FTIR spectroscopy and identified as a suitable catalyst material for sensing platform. Experiments were conducted to typify the electrode as a sensor for the estimation of hydrazine. The SG-modified electrode exhibited overpotential of hydrazine oxidation at 0.31 V, which is lower than many other electrochemical sensors. The linear calibration plots were obtained over the range of 0.5–6 ${\mu}$M in chronoamperometry and the limit of detection is as low as 0.25 ${\mu}$M. It is one of the finest reports in terms of high sensitivity and low limit of detection has also been achieved. It is concluded that SG exhibited an efficient sensor platform for hydrazine determination.
