One of the main achievments of Marcus electron-transfer theory is the predictions of the existence of normal and inverted regions.Conformation of the existence of inverted regions has been a hot point by experiments.The direct el ectron-transfer rate constants were worked out between conduction band and the γ-MnO2/K3[Fe(CN)6] soluton interface by measuring the flat band potentials and the Tafel plots and Marcus type inverted regions were observed from logket～V(a pplied bias potential) curve.Furthermore,the existence of inverted regions was d emonstrated theoretically in direct electron transfers between the semiconductor /electrolyte interface.
