What Materials are Commonly Used for Hole Generation?
Materials such as titanium dioxide (TiO2), zinc oxide (ZnO), and cadmium sulfide (CdS) are commonly used in photocatalysis due to their ability to generate electron-hole pairs upon light absorption. These materials are chosen based on their band gap, which determines the energy required to excite electrons from the valence band to the conduction band, thereby generating holes.
