Photo-induced charge transfer in the Ag–TiO2 interface: a Temporal profiles of transient absorption decays of Ag/TiO2 and TiO2 films, probed at 460 and 650 nm after excitation at 355 nm (350μJcm−2, 1 Hz) and b two-dimensional plot of the transient absorption spectrum of an Ag/TiO2 (5 s) film after UV excitation (355 nm, 350μJcm−2). c Photocurrents at different applied potentials under UV irradiation and d electrochemical impedance spectroscopy at 0 V vs. Ag/AgCl for TiO2 and Ag/TiO2 under dark and illumination conditions (inset: electrical circuit used for the data fitting)
