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.

A method of making an electrode, comprising:
- autoclaving a mixture comprising a tin salt, a sugar and water to form a reaction product;
- vacuum heat treating the reaction product to form carbon-doped tin oxide nanoparticles;
- coating a surface of a fluorine-doped tin oxide substrate with the nanoparticles to form the electrode.
