My research aims to improve renewable energy technologies through the use of new and better materials. I work both at a fundamental level to determine material properties but also investigate performance in applications including photovoltaics and hydrogen production.
Hydrogen production via photocatalytic water splitting
Hydrogen can be produced directly from water and produces only water when burned, making it a completely renewable and non-polluting fuel source that could replace fossil fuels. However, current methods to produce hydrogen requires a significant amount of energy and it is still not economically competitive with oil and gas.
My research aims to produce light absorbing materials which can produce hydrogen (H2) from water (H2O) using only energy from sunlight to drive the reaction.
To achieve this, We prepare metal oxides which absorb light, store the energy, and then use the energy to split water. This process is enhanced with co-catalysts to drive hydrogen evolution or oxygen evolution. These co-catalysts are often rare and expensive materials (platinum or rhodium), so we deposit few-atom cluster co-catalysts which we find improve performance and reduce the amount of precious materials used.
My recent research in reducing the cost of hydrogen production materials is shown in the video:
Finally, we develop instruments to monitor photocatalysis under varied conditions (temperature, pressure, light illumination intensity) to determine the optimal conditions for solar driven photocatalytic hydrogen production.
