Bismuth-oxy-iodate (BiOIO3) nanostructure was successfully synthesized by a microwave-assisted method. Phase, morphology, and optical properties of the as-synthesized products were characterized by XRD, SEM, TEM, FTIR, and UV-visible spectroscopy. In this research, the as-synthesized products were composed of orthorhombic BiOIO3 nanoplates. The Bi-O bending vibration showed a strong band at 513cm(-1) and I-O bending vibration showed as weak bands at 685 and 773cm(-1). The photocatalytic properties were evaluated through photodegradation of rhodamine B (RhB) induced by xenon visible radiation. The BiOIO3 nanoplates synthesized by 360W microwave for 60min with energy band gap of 2.75eV have the highest photocatalytic activity of 98.9% within 60min.
