  • Patent number: 9082700
    Abstract: An ultraviolet treatment method is provided for a metal oxide electrode. A metal oxide electrode is exposed to an ultraviolet (UV) light source in a humid environment. The metal oxide electrode is then treated with a moiety having at least one anchor group, where the anchor group is a chemical group capable of promoting communication between the moiety and the metal oxide electrode. As a result, the moiety is bound to the metal oxide electrode. In one aspect the metal oxide electrode is treated with a photoactive moiety. Exposing the metal oxide electrode to the UV light source in the humid environment induces surface defects in the metal oxide electrode in the form of oxygen vacancies. In response to the humidity, atmospheric water competes favorably with oxygen for dissociative adsorption on the metal oxide electrode surface, and hydroxylation of the metal oxide electrode surface is induced.
