Abstract
Electroanalytical performance of electrodeposited platinum nanoparticles (PtNPs), selenium nanoparticles (SeNPs), and tin oxide nanoparticles (SnO2NPs) on the surface of bare fluorine-doped tin oxide (BFTO) (PtNPs-SeNPs-SnO2NPs@BFTO) nanocomposite was used as an non-enzymatic electrochemical sensor towards detection of H2O2. The surface morphology and characterization of PtNPs-SeNPs-SnO2NPs@BFTO was studied by field emission scanning electron microscopy (FESEM) and EDS mapping. The Morphology of PtNPs-SeNPs-SnO2NPs@BFTO showed flower, spherical and irregular shapes by FESEM investigation. X-ray photoelectron spectroscopy was used to investigate the elemental composition of platinum, selenium, tin, oxygen, and fluorine on the PtNPs-SeNPs-SnO2NPs@BFTO surface. The synthesized PtNPs-SeNPs-SnO2NPs@BFTO electrochemical sensor was used for electro-catalytic detection of H2O2. The linear concentration range of the PtNPs-SeNPs-SnO2NPs@BFTO was 0.01 to 54 mM, with a high sensitivity of 104.8 mA mM−1 cm−2 and a low detection limit of 0.01 mM. The interference study of PtNPs-SeNPs-SnO2NPs@BFTO based sensors showed high selectivity towards H2O2 with interfering agents, including glucose (GU), ascorbic acid (AA), urea (UA), sucrose (SU), sodium chloride (SC), and sodium selenite (SS).
