Increased efforts to reduce carbon dioxide (CO2) emissions have resulted in significant development of clean energy technologies such as water splitting and conversion of CO2 to fuels. Both these technologies make use of electrodes, whose surface areas are important for efficient energy production. Previous work has shown that hematite (α-Fe2O3) serves as an excellent photoelectrode material for water splitting. Meanwhile, nanocrystalline copper (Cu) has shown to be the only material that aids the reduction of carbon monoxide, which is an important step in the conversion of CO2 to fuels. In this work, highly nanostructured α-Fe2O3 and Cu are deposited onto surfaces using non-traditional synthetic techniques.
