Cu2ZnSnS4/MoS2/CNT- ternary heterostructures for paracetamol determination

Paracetamol (PAR) as a promising medicine being frequently used as pain reliever and in treatment of fever nonetheless may result in liver problems on excessive use. To counter this, here we have reported a novel electrochemical sensor utilizing hybrid nanocomposites of CZTS/MoS2/CNT. Ternary hydrothermal method is followed to develop a functionalized matrix of CZTS/MoS2 over the surface of carbon nanotube (CNT) network. Fast electrochemical sensors with excellent conductivity and chemical durability are constructed using carbon nanotubes. Material characterization techniques, X-Ray Diffraction spectroscopy (XRD), scanning and tunnelling electron microscopies (SEM and TEM) and energy dispersive X-ray spectroscopies is being employed to analyse as synthesized CZTS/MoS2/CNT. The electrochemical sensor is constructed by pasting an adequate amount of slurry composed CZTS/MoS2/CNT composite over a carbon paste electrode (CPE) functioning as working electrode. With the help of this investigation, the problematic identification of paracetamol from biological entities, such as blood, stomach, small intestine or gastro intestinal tract, has been overcome. Probably for the first-time, turnery CZTS/MoS2/CNT sensor is studied to sense PAR electrochemically. The sensitivity of PAR, identical to a promising sensitivity of 16 mu A at 10 ppm paracetamol is achieved. The work clearly demonstrates the electrochemical sensing properties of ternary CZTS/MoS2/CNT towards PAR.
