半导体是在照明下与光发射二极管(LED)或其他光源产生的人造光合成的精细有机分子合成的。[3-5]无论尺度及其介导的反应如何,从非常一般的角度来看,光催化剂都可以通过光诱导的电子转移(PET)从一种试剂流动到另一种试剂,如图1所示。Assuming that a reaction mixture is composed of an n-type semiconductor that has a potential of the valence band ( E VB , V vs reference electrode (RE)) more positive than the oxidation potential of the electron donor ( E (D • + /D), V vs RE) and a potential of the conduction band ( E CB , V vs RE) more negative than the reduction potential of the electron acceptor ( E (A/A • − ),v vs re),相应PET的驱动力(δg0,eV)可以通过公式表示[6,7]
