What Factors Affect the Efficiency of Photogenerated Electrons?
Several factors influence the efficiency of photogenerated electrons in catalytic processes:
Light Absorption: The ability of the semiconductor to absorb light and generate electron-hole pairs. Charge Separation: The separation and migration of photogenerated electrons and holes to the surface of the catalyst. Recombination Rate: The rate at which electrons and holes recombine without contributing to the catalytic reaction. Surface Properties: The surface area and active sites available for the catalytic reaction. Doping and Co-Catalysts: The use of dopants or co-catalysts to enhance charge separation and reduce recombination.
