Stephanie Gray demonstrates how to synthesize nanoscale Tungsten Oxide WO3. The final product can then be made into a film, which then can be used to measure its semiconducting and gas evolving properties using an electrochemistry and irradiation instrument in the laboratory, respectively. Tungsten Oxide is a oxygen evolving photocatalyst. When it combined with a hydrogen evolving photocatalyst as apart of a tandem water splitting system, it can convert solar energy and water into usable hydrogen fuel.
