Photoelectrochemical properties and reaction mechanism of different-structured SnO2-TiO2 composites. (a) The liquid-phase photodegradation of MO under UV light irradiation of different samples; the insert shows the degradation efficiency of the unit area. (b) Transient photocurrent responses of different samples under Xe lamp irradiation. (c) Electrochemical impedance spectroscopy (EIS) Nyquist plot of NT, NF, and Mix samples, respectively. (d) A proposed schematic illustration showing the reaction mechanism for photocatalytic degradation of organic pollutants under UV light irradiation.
