Novel graphene oxide@aluminum oxide@manganeseoxide-based ternary nanocomposites: facile synthesis and characterization for catalytic treatment of targeted industrial effluents

Herein, graphene oxide anchored Aluminum Oxide doped Manganese Oxide nanoparticles based ternary nanocomposites were prepared via simple dispersion method to catalytically reduce organic dyes in aqueous media. Structural, morphological, and thermal stability features of the prepared nanocomposite was investigated through various characterization techniques, for example, X-ray Diffraction, Fourier Transform Infrared. Spectroscopy, Energy Dispersive X-ray Spectroscopy and Thermal Gravimetric Analysis. The catalytic potential of the nanocomposite was investigated against catalytic degradation of Methylene Blue, and Methyl Orange. Results indicate that the ternary nanocomposites provide agreeable catalytic capacity towards Methylene Blue reduction, whereas, remarkably efficient towards Methyl Orange degradation. In addition, the effect of catalyst dose on the reduction rate of the targeted dyes was studied. The evaluated kinetic parameters, for example, reduction rate constant and R² values recommend the usability of the fabricated nanocomposites in industrial domain.
