【 摘 要 】

(α, β)-CoV3O8/V4O7 nanocomposites have been successfully synthesized through a facile hydrothermal method at low temperature. The structural properties of these nanocomposites are characterized via Powder X-ray diffraction, Fourier Transform Infrared spectroscopy (FTIR), Scanning electron microscopy (SEM), and X-ray energy dispersive spectroscopy (EDX) analysis. Synthesized nanocomposites were determined to have an approximate crystalline size of 3.72 nm, and SEM imaging exhibited aggregated irregular rectangular shaped nanocomposites. Adsorption kinetics and isotherms were examined, and the outcomes showed that the adsorption followed pseudo-second-order kinetic model and Langmuir isotherm. Adsorption of methylene blue dye was investigated using (α, β)-CoV3O8/V4O7 nanocomposites at varying concentrations of the dye. 20 μM aqueous solution of methylene blue was found to have a high adsorption efficiency of almost 95% in 5 minutes.
