title: Phase transformation and enhanced photocatalytic activity of S-doped Ag2O/TiO2 heterostructured nanobelts.
abstract: Ag2O/TiO2 nanobelt heterostructures have been found to possess high ultraviolet photocatalytic activity, but a poor cycling performance. After a S-doping treatment, the obtained Ag2O/Ag2S2O7/TiO2 heterostructured nanobelts exhibited an enhanced and stable photocatalytic activity under both ultraviolet and visible light irradiation, which was exemplified by photo-degradation of organic pollutants and photocurrent response measurements. Meanwhile, the crystal structure and phase transformation of Ag2O, Ag2S2O7 and Ag2S were studied by XRD and XPS measurements.
