Description
Summary:Hydrogen peroxide (H 2 O 2 ) electrochemical sensing is a vital area of research and application due to the widespread use of hydrogen peroxide in various industries and its importance in biological systems. Due to the high oxidation potential of H 2 O 2 , it must be sensed accurately and in a real-time basis for usage in medical, commercial and defence sectors. In the present work, vanadium(IV) oxide (VO 2 ) nanoparticles were synthesized and deposited on conductive fabric for the sensing of H 2 O 2 . The synthesized nanoparticles were characterized using X-ray powder diffractometer, Fourier transform infrared spectroscopy, field emission scanning electron microscopy and X-ray photoelectron spectroscopy. The electrochemical study of the nanoparticles was investigated by means of differential pulse voltammetry and cyclic voltammetry. Under optimum circumstances, the fabricated electrode presented a linear response in the range of 100–700 µM by differential pulse voltammetry analysis with a detection limit and quantification limit of 25.6 µM and 77.57 µM, respectively. The sensor possesses outstanding anti-interference ability while sensing H 2 O 2 . The fabricated sensor is highly stable and highly reproducible.
