Nanostructured Metal Oxide Electrodes for Solar Hydrogen Generation: Nano Seminar Series

Seminar: Micro/Nano Electro Mechanical Systems | September 6 | 2-3 p.m. | 390 Hearst Memorial Mining Building

Prof. Yat Li, UC Santa Cruz, Chemistry and Biochemistry

Berkeley Nanosciences and Nanoengineering Institute

This talk will present highlights of the latest results of studies directed at developing oxygen-deficient metal oxides, including TiO2, WO3, α-Fe2O3 and BiVO4 nanostructures as electrode materials, which show significantly enhanced performance in applications for solar hydrogen generation.

The enhanced photoelectrochemical performance for water oxidation is attributed to improved electrical conductivities by controlled incorporation of oxygen vacancies as shallow donors for metal oxides.

The potential of these oxygen-deficient metal oxides for other solar energy conversion processes, such as photocatalytic water splitting, urea splitting, and microbial electrolysis reactions will also be discussed.
