The photogenerated holes

Webb13 apr. 2024 · In some cases of the photocatalytic oxidation of organic compounds using photogenerated holes, the photogenerated electrons are consumed by the sacrifice agents. To balance this, a novel photocatalytic strategy that capable of synchronously utilizing photogenerated electrons and holes are developed [ 27, 28 ]. Webb3 apr. 2024 · The separation of photogenerated electrons and holes is the core step of photodegradation. The higher the separation rate of photoinduced charge is, the more free radicals are generated during the degradation process, which is beneficial to the photocatalytic performance [ 36, 42 ].
