Abstract
We describe a simple method for preparing the hybrid material of Pt nanoparticles (NPs) supported on carbon-coated SnO(2) nanospheres (Pt-SnO(2)@C). The as-prepared Pt-SnO(2)@C nanocomposite was characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). The presence of carbon-coated SnO(2) nanospheres (SnO(2)@C) remarkably improves the electrocatalytic activity of Pt NPs towards hydrogen peroxide (H(2)O(2)) oxidation. The Pt-SnO(2)@C nanocomposite modified glassy carbon (GC) electrode exhibited enhanced amperometric response to H(2)O(2), with detection limit of 0.1 μM and sensitivity of 241.1 μA mM(-1) cm(-2).Entities:
