Abstract

Ozone treated carbon electrodes can provide increased catalytic activity, such as in a dye-sensitized solar cell (DSSC) or other electrochemical device or other device that could benefit from an increased catalytic activity, such as lithium ion or other batteries, hydrogen fuel cells, or electroanalytical instruments. Devices, methods of making, and methods of using are discussed.
