A novel auto-combusted synthesis of MFC-800 nanoparticles: an efficient photocatalyst for degradation of industrial pollutant in environmental benign route

We have prepared MFC-800 nanoparticles (MnFe 2 O 4 nanoparticles, calcinated at 800 °C) by a novel auto combustion technique for the degradation of TY (titan yellow) dye under the natural source of light and reduction process (aromatic nitro compounds, Ar-NO 2 to Ar-NH 2 ) in green circumstances. Different characterization techniques like FT-IR, UV–Vis, XRD, and SEM–EDX have been engaged for the confirmation of the production of MFC-800 nanoparticles. Various parameters were examined for obtaining better results in terms of degradation efficiency (%), like the amount (mg) of MFC-800 nanoparticles, dye concentration (ppm), amount (ml) of TY dye, and pH of TY dye solution. The prepared MFC-800 nanoparticles showed excellent catalytic activity of 94% for TY dye degradation. The MFC-800 nanoparticles in combination with NaBH 4 smoothly reduces the 4-NP (4-nitrophenol) to 4-AP (4-aminophenol) in 75 s. Synthesized MFC-800 nanoparticles were easy to recover with the help of an external magnet from the reaction mixture. The developed system is simple and cost-effective, and no additional chemicals were used for the degradation process.
