Ultrasound-assisted synthesis of YbVO4 nanostructure and YbVO4/CuWO4 nanocomposites for enhanced photocatalytic degradation of organic dyes under visible light

Abstract

YbVO nanostructure and YbVO/CuWO nanocomposites were successfully synthesized using sonochemical method, for the first time. In this disquisition, we tried to compare various parameters and reaction conditions on size, morphology, and uniformity of as-obtained samples. To reach optimum condition, some parameters including time, power, temperature, and solvent were investigated. The structural, morphological, optical, and magnetic properties of as-obtained products were characterized by some techniques such as FT-IR, XRD, EDS, SEM, TEM, UV-Vis, and VSM. Furthermore, due to occurrence of red shift in nonanocomposite, during the coupling of CuWO into YbVO, photocatalytic and optical properties of final products were improved which lead to improve photo-destruction efficiency for methylene blue from 65% to 100%, during 120 min irradiation. The effect of the ultrasonic radiation on the photocatalytic behavior of YbVO/CuWO shows that methylene blue pollutant destruction was about 100% with ultrasonic wave and 61% in the absence of ultrasonic radiation.

Room-Temperature Synthesis and Optical Properties of NdVO4 Nanoneedles

“…Thus, lanthanide-containing materials find applications as laser host matrices, optical polarizers, thermophosphors, sensors, solar cells, scintillators for γ-rays detection, in nuclear waste storage, ionic conductors, catalysts or photocatalysts. [1][2][3][4][5] The efficiency of the 4f n excitations in a lanthanide ion can be enhanced through a charge transfer from a host material with a higher absorption coefficient. The orthovanadate group, VO 4 3− , is a good host for the trivalent ion because it can excite most of the lanthanide ions via the charge transfer transition within the VO 4 3− group, followed by an energy transfer to the emissive lanthanide ion.…”
