||Hydrogen is a promising, environmentally-friendly fuel source for replacing fossil fuels in transportation and stationarypower
applications. Currently, most hydrogen is produced from non-renewable sources including natural gas, oil, and coal.
Photoelectrochemical (PEC) water splitting is a new renewable energy technology that aims to generate hydrogen from water using
solar energy. When light is absorbed by the photocatalyst, an electron-hole pair is generated that interacts with water molecules in a
surface reduction-oxidation reaction to decompose the water into hydrogen and oxygen. The current challenge in PEC water splitting
is finding low-cost, stable materials with good visible light absorption and high efficiency for water splitting. Polymers such as
thiophene have demonstrated promising capabilities as photocatalysts due to its favorable band structure for both solar absorption
and photocatalysis by electropolymerizing films for vertical transfer of electrons. This project aims to improve the performance of PEC
devices for water splitting by developing new high surface area photoelectrodes surrounded by a thin layer of electroplated polymers.
