The current study aims to synthesize and characterize Calcium Molybdate-Graphene Oxide (CaMoO4@GO) nanocomposite under ultrasonic irradiation. Primarily, degradation of Methylene blue (MB) under Uv-Vis light was investigated to measure the photocatalytic properties of the as-synthesized CaMoO4@GO nanocomposite. In addition, various graphene oxide concentrations were applied to investigate its impact on the optical and photodegradation properties of calcium molybdate. X-ray diffraction (XRD), scanning electron microscopy (SEM), and spectra energy dispersive analysis of X-ray (EDS) were used to characterize CaMoO4@GO nanocomposite. DRS results demonstrated that GO influenced significantly the optical properties of CaMoO4 as much as band gap of CaMoO4@GO nanocomposite shows a redshift in comparison with pure CaMoO4. Consequently, photocatalytic results demonstrated that adding GO causes to increase photodegradation of MB form 65% (CaMoO4) to 89% (CaMoO4@GO).

“…Among molybdates, CaMoO4 is considered an outstanding matrix material for the synthesis of highly applicable luminescent materials due to its excellent physical and chemical properties [17][18][19][20][21][22][23][24] . Moreover, CaMoO4 exhibits a tetragonal structure and space group I41/a 25 with a shared edge 27 . In addition, CaMoO4 based materials are also important materials that can be used in various applications such as photoluminescence (PL) and microwave applications [28][29] , scintillators [30][31] , photocatalysis 7 , and the emission of light in the blue-green region of the electromagnetic spectrum after excitation with UV light 32 .…”

In this article, the synthesis by means spray pyrolysis method, of the CaMoO4 and rare earth cation (RE 3+)-doped CaMoO4:xRE 3+ (RE 3+ = Eu 3+ , Tb 3+ , and Tm 3+ ; and x= 1%, 2%, and 4% mol) compounds is presented. The as-synthesized samples were characterized using x-ray diffraction (XRD), Rietveld refinement, field emission scanning electron microscopy (FE-SEM), Raman spectroscopy, and photoluminescence (PL) spectroscopy. To complement and rationalize the experimental results, first principle calculation, at density functional theory level, have been performed to analyze the band structure and density of states. In addition, a theoretical method based on the calculations of surface energies and Wulff construction was applied to obtain the morphology transformation of the CaMoO4 and CaMoO4:RE 3+ microstructures. The experimental morphologies can be observed in the FE-SEM images. The PL behavior of the co-doped samples exhibited well-defined bands in the visible region. The samples with 2% and 4% of RE 3+ released white emission according to the chromaticity coordinates (0.34, 0.34) and (0.34, 0.33), respectively. Present results provide not only a deep understanding of the structure-property relationships of CaMoO4-based phosphor, but also can be employed as a guideline for the design of the electronic structure of the materials and the fabrication of photo-functional materials with optimal properties, which allows for the modeling of new phosphors for applications in solid-state lighting.

“…[6][7][8] Among these, SrMoO 4 shows distinctive electronic as well as physical and chemical properties with low phonon energy due to its body-centered scheelite crystal structure. 9 Different nanostructures of SrMoO 4 NPs have been applied in some areas, such as in the hydrogen evolution reaction (HER), 10 photocatalytic/photoelectrocatalytic activity, 11,12 and host materials in light-emitting phosphors. 13 However, there are only few reports on the use of SrMoO 4 as a chemical sensor material.…”
