反應(yīng)時就會形成如 S1的穩(wěn)態(tài)中間體和如 T T2的過渡態(tài)中間體。這個過程相對于之前需要少得多的能量。 The absorption of a photon with energy larger than the band gap of the semiconductor can excite an electron from the valence band to the conduction band. This band–band excitation produces the reductive conduction band electrons (ecb) and oxidative valence band holes (hvb+). 超氧自由基負離子 能壘很小 的反應(yīng) (1) it possesses suitable redox potentials of conduction band and valence band to ensure the simultaneous reduction of O2 and oxidation of the H2O or anic pounds。 (B) 鄰位的兩個羥基與氧原子形成二配位的螯合共價鍵。
