Preparation of Bi2WO6 nanoplates modified by Nd doping photocatalyst for rhodamine B dye degradation

0-3% Nd-doped Bi2WO6 nanoplates were synthesized via hydrothermal method. The Bi2WO6 without and with Nd doping can be indexed to the single phase of orthorhombic Bi2WO6 nanoplates with orientation growth in the along the [001] projection by XRD, SEM and TEM analysis. The 2% Nd-doped Bi2WO6 nanoplates shows the maximum photocatalytic activity under visible light irradiation owing formation of oxygen vacancies as recombination centers with decreased rate of recombination carries charge pairs after Nd doping. Furthermore, the radical scavenger of RhB degradation over 2% Nd-doped Bi2WO6 nanoplates was analyzed to discuss the mechanism of the photodegradation possible in this research.
