Sol–gel auto-combustion synthesis of enzyme-assisted MnFe2O4/MWCNTs for enhanced photocatalytic degradation of methylene blue and eco-toxicity mitigation
Experimental study demonstrates 91% photocatalytic degradation of methylene blue using green nanocomposites, indicating effective wastewater detoxification for agricultural reuse.
Key Points
Synthesize green, enzyme-assisted manganese ferrite and carbon nanotube nanocomposites to evaluate their photocatalytic efficiency and environmental detoxification capabilities in wastewater treatment.
Synthesized MnFe2O4 nanoparticles via banana peel enzyme-assisted sol–gel auto-combustion and incorporated multi-walled carbon nanotubes (MWCNTs).
Characterized structural, morphological, and electrical properties using XRD, FTIR, SEM, BET surface area analysis, and EIS.
Tested solar-driven photocatalytic degradation of methylene blue under varying conditions and evaluated treated water safety using a barley seed germination assay.
The enzyme-assisted MnFe2O4/MWCNTs nanocomposite achieved a peak methylene blue degradation efficiency of 91% under optimal parameters (25 ppm dye, 1.25 g/L catalyst, pH 7, 100 min sunlight).
Barley seeds irrigated with the photocatalytically treated water exhibited enhanced germination rates and seedling vigor compared to those exposed to untreated dye solution.
