A simple sonochemical approach for synthesis of cadmium molybdate nanoparticles and investigation of its photocatalyst application

Abstract

Nanoparticles cadmium molybdate was prepared by ultrasonic method using cadmium(II) nitrate hexahydrate and ammonium heptamolybdate tetrahydrate were used as precursor materials. To the best of authors' knowledge, it is the first time that cadmium molybdate was synthesized by ultrasonic method. The as synthesized nanostructures were characterized by X-ray diffraction, scanning electron microscopy, X-ray energy dispersive spectroscopy, and ultraviolet-visible spectroscopy. To evaluate the catalytic properties of nanocrystalline cadmium molybdate, the photocatalytic degradation of 2-naphthol under visible light irradiation was carried out.

Synthesis of Photoactive Materials by Sonication: Application in Photocatalysis and Solar Cells

“…Furthermore, application of ultrasound irradiation to a photocatalytic system might enhance both the bulk and localized mass transport and consequently expedite the molecular contact and the photocatalytic activity [ 1 , 2 , 4 – 6 ]. A considerable number of novel photocatalysts with novel nano-/microstructures (e.g., ZnWO 4 [ 7 ], CdMoO 4 [ 8 ], V 2 O 5 [ 9 ], CuMoO 4 [ 10 ], TiO 2 /Bi 2 O 3 [ 11 ]) have been prepared by means of ultrasound-assisted methodology. In this subsection, we would like to focus the readers’ attention on ultrasound-promoted procedures for the preparation of photocatalysts, and the potential application of these materials in the photocatalytic degradation and selective oxidation of organic compounds.…”

Nanocrystalline EuVO4: synthesis, characterization, optical and photocatalytic properties

“…Metallic nanoparticles are characterized by a high surface area to volume ratio and exhibit prominent spatial uniformity and structural stabilities [1][2][3][4][5][6][7][8]. Photocatalytic degradation of organic compounds on semiconductor surface has attracted increasing attention in recent years because the technique is regarded as one of the most promising and efficient solution for the removal of organic pollutants [9][10][11]. Rare earth orthovanadate is an important class of inorganic functional materials which has been intensively investigated in recent times due to its attractive properties and is widely exploited as phosphors [12], catalysts [13], polarizer [14] and laser host materials [15].…”
