Abstract
An electrode which includes nanoparticles of a carbon-doped tin oxide of formula C—SnO2-x where x=is from 0.001 to 0.1, having surface oxygen vacancies. The electrode includes a fluorine-doped tin oxide substrate. A film of the nanoparticles is present on at least one surface of the fluorine-doped tin oxide substrate. The surface oxygen vacancies correspond to an O 1s peak shift of 0.5-2 eV in the X-ray photoelectron spectroscopy (XPS) for C—SnO2-x compared to C—SnO2 without surface oxygen vacancies.
Claims8
A method of detecting hydrogen peroxide at a concentration of 1 μM to 20 μM in an alkaline solution,
- immersing an electrode into an electrolytic cell containing the alkaline solution,
- applying an electrical potential to the electrolytic cell and recording a peak current, then
- determining a concentration of the H2O2 in the alkaline solution;
- wherein the electrode comprises:
- nanoparticles of a carbon-doped tin oxide of formula C—SnO2-x wherein x=is from 0.001 to 0.1, having surface oxygen vacancies,
- a fluorine-doped tin oxide substrate,
- wherein a film of the nanoparticles is present on at least one surface of the fluorine-doped tin oxide substrate,
- wherein the surface oxygen vacancies correspond to a O 1s peak shift of 0.5-2 eV in the X-ray photoelectron spectroscopy (XPS) for C—SnO2-x compared to C—SnO2 without surface oxygen vacancies.
