The effect of green synthesized MnFe2O4/TiO2 nanocomposite mass on methylene blue degradation in photocatalyst

Abstract

The growth of the textile industry has worsened the problem of properly disposing of liquid waste, including industrial dyes, in an environmentally friendly manner. This study aims to simulate the degradation of industrial dyes, especially methylene blue, through photocatalytic tests using MnFe2O4/TiO2 nanocomposite. MnFe2O4/TiO2 nanocomposite were manufactured using a green method, green synthesis, with varying masses of 0.02 grams, 0.04 grams, 0.06 grams, 0.08 grams, and 0.10 grams. Furthermore, the coprecipitation method is employed with the objective of creating magnetic particles that are on the scale of nanometers. The X-ray diffraction (XRD) spectra of MNPs indicates a crystalline size of 13.3 nm. The infrared Fourier transform analysis reveals the presence of Mn-O, Fe-O, and Ti-O functional groups at wave numbers of 439.1 cm-1, 587.1 cm-1, and 586.8 cm-1, respectively. The presence of these functional groups indicates the successful synthesis of MnFe2O4/TiO2 nanocomposite. The band gap of MnFe2O4/TiO2 nanocomposite is within the range of 3 electron volts (eV). MB, an organic compound dye, may be destroyed using photocatalytic processes by exposing it to UV light. The degradation of the substance achieved a complete reduction of 100% within a duration of 20 minutes during the photocatalytic process, using an ideal mass of 0.02 grams. The MnFe2O4/TiO2 nanocomposite possess the potential to be frequently utilized due to their capability in separating from the degradation solution. Hence, our results indicate that the MnFe2O4/TiO2 nanocomposite with a mass of 0.02 grams has the highest efficiency in degrading methylene blue, even when the mass is varied.
