Green synthesis of mesoporous 2D Mn2O3/rGO nanocomposite for effective removal of methyl orange

Green synthesis of Di-Manganese tri oxide mesoporous structure (super Nano porous) Sheets (Mn2O3-rGO-NS), Graphene oxide Nano sheets (GO) and Mn2O3-rGO-NS Nano sheets Composite (Mn2O3-rGO-NS) were prepared via Thermal decomposition, seconds timescale water electrolytic oxidation and sonication method respectively. The prepared samples were characterized via X-ray diffraction, FESEM, TEM , and FTIR. Average crystallite size was found about 38 and 26 nm for Mn2O3-NS and Mn2O3-rGO-NS, respectively. Mn2O3-rGO-NPs morphology revel Nano porous sheets within average 35 nm and 26 in pores diameter and thickness respectively. Mn2O3-NS act distributed on and between graphene sheets creating macro and Nano-pores. The obtained results showed that the characteristics of the a-Mn2O3-rGO-NS sheets were improved by the addition of rGO sheets. Methyl orange (MO) dye adsorption onto Mn2O3-rGO-NS Composite was investigated at various adsorption parameters, including pH, adsorbent quantity, and time. It was discovered that the adsorption behavior complies with the intra-particle diffusion model and the Friedendlich isotherm. Methyl orange in aqueous media may be eliminated 99.3% by Mn2O3-rGO-NS Composite.
