Synthesis of an Ag3PO4/Nb2O5 Photocatalyst for the Degradation of Dye

In this work, the photocatalytic performance of Ag3PO4, Nb2O5 and Ag3PO4/Nb2O5 hybrid photocatalysts to degrade methyl orange dye, MO, in an aqueous solution under visible light irradiation was evaluated. The Ag3PO4 photocatalysts, with various Ag Nb molar ratios, were prepared using a facile precipitation method. characterized by X-ray diffraction, UV–Visible, Photoelectron, Photoluminescence spectroscopies. Upon addition band gap energy decreased from 3.0 eV 2.7 eV, indicating possible use irradiation. All catalysts exhibited higher than degrading dye 23-watt catalyst, mole ratio 2:1, fastest MO degradation rate 7.3 × 10−2 min−1, which is twice faster that Ag3PO4. catalyst also shows better stability, as it reusable for up six experimental cycles while maintaining its activity above 60%.
