Photocatalytic degradation studies of malachite green dye by hydrothermally synthesized Cobalt Vanadate nanoparticles

Cobalt vanadate (Co3V2O8) nanoparticles were prepared by a hydrothermal process using ammonia metavanadate and cobalt nitrate as precursors and calcined at 450 °C to obtain pure Co3V2O8 nanoparticles. The sample was characterized by scanning electron microscopy, X-ray diffraction, Fourier transform infrared, and UV-visible diffuse reflectance spectroscopy. The characterization analysis confirmed variations in the structure, shape, […]

Synthesis and characterization of new spinel Mn0.5Cu0.5Cr2O4 and degradation of Malachite Green from wastewater in comparison with CuCr2O4

In this study phase- pure new spinel structure, Mn0.5Cu0.5Cr2O4 was prepared by hydrothermal method successfully and the degradation of Malachite green as an organic pollutant was investigated and compared with CuCr2O4. Purification of obtained nanoparticles was measured by using X-ray diffraction method (XRD) in which crystal structure and the structural properties were studied by using […]

Hirshfeld surface analysis of solid-state synthesized NiFe2O4 nanocomposite and application of it for photocatalytic degradation of Water pollutant dye

The present work reports the Hirshfeld surface analysis and photocatalytic performance of NiFe2O4 nanomaterial. Hirshfeld surface analysis was performed to understand the interaction properties of the NiFe2O4 compound. The active sites including π-π interactions are studied by the analysis. The Hirshfeld data showed that the two wings in the O…O and O…Ni diagrams are created […]
