Fe2O3@MgO, Fe2O3@Mn2O3, and Fe2O3@Co3O4 nanocomposites were synthesized using a two-pot wet chemical procedure. The study included analysis of structure, optical properties, surface morphology, elemental composition, porosity, surface area, functional groups, and photocatalytic activity. Experimental results were obtained through techniques like PXRD, PL, DRS, SEM, EDAX, BET, FTIR, and tests using MB, RhB, Phenol, COD, and radical scavengers.
The Fe2O3@MgO, Fe2O3@Mn2O3, and Fe2O3@Co3O4 nanocomposites were developed using a two-pot wet chemical procedure. The structure and the phase were confirmed using the Powder X-Ray diffraction tool (PXRD). The optical properties of the prepared materials were analyzed using Photoluminescence (PL) and Diffuse Reflectance Spectroscopy (DRS) technique. Surface morphology and elemental composition of the prepared samples were studied by Scanning Electron Microscope (SEM) and Energy Dispersive X-Ray Spectroscopy (EDAX). The porosity and the surface area of the materials were studied by Brunauer-Emmett-Teller (BET) analysis. The functional group present in the prepared material is analyzed by Fourier transforms IR analysis (FTIR). The photocatalytic analysis was done using Methylene Blue (MB), Rhodamine B (RhB) and Phenol. Further the mineralizations of the pollutants are studied by COD experiment and also the radical scavenger experiments are carried out.
