Abstract: 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 proposed correspondingly. It is hoped that the synthesised flexible AgVO₃ nano paper would also have the other applications in the fields, such as Li-ion battery, gas sensing, super capacitor, and so on.
