© 2018 Elsevier B.V. Herein, we report the synthesis of sulfur-doped carbon quantum dots (S-CQDs) chemically incorporated with iron oxide nanoparticles (S-CQDs/Fe 2 O 3 ) using hydrothermal synthesis strategy. The as-synthesized nanocomposite was characterized using powder X-ray diffraction, fourier transform infrared spectroscopy, transmission electron microscope, thermogravimetric analysis, and energy dispersive X-ray spectroscopy. We have analyzed the clear electrochemical kinetics of the S-CQDs/Fe 2 O 3 nanocomposite modified glassy carbon electrode. Addition to this, electrochemical sensing property of S-CQDs/Fe 2 O 3 /GCE towards the detection of antipsychotic drug olanzapine (OLZ) was explored. Remarkably, S-CQDs/Fe 2 O 3 /GCE has shown the good electrocatalytic activity for OLZ oxidation and also exhibits a very low detection limit and sensitivity of about 0.006 μM and 0.88 μA μM −1 cm −2 respectively. Further, the proposed sensor has applied for the detection of OLZ in urine samples.
