What Are the Key Components of Photocatalytic Reduction?
1. Photocatalyst: The material that absorbs light and generates electron-hole pairs. Common photocatalysts include titanium dioxide (TiO2), zinc oxide (ZnO), and various metal-organic frameworks (MOFs). 2. Light Source: Typically, ultraviolet (UV) or visible light is used to excite the photocatalyst. 3. Substrate: The molecule that undergoes reduction, such as CO2 or water. 4. Electron Donor: Often needed to replenish the electrons in the photocatalyst, preventing recombination of electron-hole pairs.
