The study on flexible AgVO 3 nano paper and its visible light photocatalytic activity

By means of the facile hydrothermal method, the ultralong β-AgVO3 nanobelts have been synthesised successfully. The properties of the as-prepared β-AgVO3 nanobelts were investigated by the characterisations, such as scanning electron microscope (SEM), X-ray diffraction (XRD), and UV-vis diffuse reflectance spectrum (UV-vis DRS). As shown by the SEM results, the obtained nanobelts showed an ultralong length of hundreds of micrometres and the width in the range of about 60-350 nm. The surface of nanobelt was also very smooth. XRD result exhibited that the AgVO3 nanobelts had a β crystal phase. By the virtue of pumping filtration of AgVO3 nanobelts solution and corresponding post processing, the flexible AgVO3 nano paper was prepared successfully. The AgVO3 nano paper exhibited a well flexibility and photocatalytic activity determined by the degradation of rhodamine B (RhB) under the visible light (λ > 420 nm) irradiation. The possible mechanism for the photocatalytic degradation of RhB by AgVO3 was also pro...
