摘要In this paper, novel Z-scheme octahedral Cu2O/Ag3PO4 composites are fabricated by a facile chemical method at low temperature. Field emission scanning electron microscope (FESEM), UV-Vis diffuse reflectance spectroscopy (DRS), energy dispersive spectrometer (EDS) and X-ray diffraction (XRD) are used to investigate the crystal structure and optical properties of the as-prepared nanocomposites. Photocatalytic activity of catalysts is displayed by methylene blue (MB) removal under visible light irradiation. The results show that photocatalytic performance of Cu2O/Ag3PO4 is much higher than that of Cu2O and Ag3PO4, and the kinetic constant k(app), of MB degradation over Cu2O/Ag3PO4 is 0.30447 min(-1), which is 7.0 and 2.1 times as high as those of Cu2O and Ag3PO4, respectively. Finally, the possible separation mechanism of electrons and holes is proposed. (C) 2017 Elsevier B.V. All rights reserved.
