Hydrothermal synthesis, structure, and optical properties of pure and silver-doped Bi<inf>2</inf>MoO<inf>6</inf>nanoplates

Abstract

© 2015 Pleiades Publishing, Ltd. The effect of Ag doping on Bi2MoO6was studied in this research. Ag-doped Bi2MoO6nanoplates were synthesized by a hydrothermal method at 180°C for 20 h. X-ray powder diffraction (XRD) and selected area electron diffraction (SAED) confirm that the products have orthorhombic Bi2MoO6structure. Bi2MoO6nanoplates were detected by transmission electron microscopy (TEM). X-ray photoelectron spectroscopy (XPS) shows peaks with binding energies of 368.84 and 374.87 eV which could be attributed to Ag 3d5/2and Ag 3d3/2, confirming that Ag is present in the Bi2MoO6matrix. Raman and FTIR spectra show the vibration of asymmetric and symmetric stretching and bending modes of MoO6octahedrons. The optical properties of products were characterized by UV-Vis spectroscopy. They show strong absorption in UV-Vis region.
