Several factors can influence the efficiency of photocatalytic processes:
1. Light Absorption: The catalyst must efficiently absorb light in the relevant wavelength range. 2. Charge Separation: Efficient separation of photogenerated electron-hole pairs is crucial to prevent recombination. 3. Surface Area: A high surface area of the catalyst can provide more active sites for reactions. 4. Morphology: The shape and structure of the catalyst can influence light absorption and electron transport. 5. Band Gap: The energy difference between the valence band and conduction band should be suitable for the desired reaction.
