Fabrication of Photocatalytic Semiconductors for Environmental Applications

The favorable combination of light absorption properties, charge transport characteristics, and excited lifetimes of some semiconductors has made possible its application as photocatalyst. Several d-metal oxides, including ZnO, TiO2, and Fe2O3, are used as n-type semiconductors and photocatalysts. Photocatalysts can degrade organic pollutants by absorbing solar light with energies higher than their band gaps. Common techniques will be utilized to characterize the prepared photocatalysts and their performance of photodegradation.
