FePO4 was successfully synthesized via a simple method as a heterogeneous catalyst for photo degradation of methyl violet 2B in aqueous solution. The FePO4 was identified by the X-ray diffraction, Fourier transform infrared spectroscopy analyses and the scanning electron microscopy image The analysis was completed by the pHPZC and the band gap energy. The photocatalytic performance of FePO4 was investigated using reduction of methyl violet 2B as a model reaction. The results showed that FePO4 had converted nearly 99% of methyl violet 2B under UV light with optimum operating conditions of 1 g L−1 of FePO4, natural pH (pH 6.75), and 10 mg L−1 of methyl violet 2B, a kinetic study was also realized. The recyclable character of the catalyst under the optimum conditions for three cycles was successfully investigated without any structural modification of the FePO4.
