The work makes use of Density Useful Principle (DFT) with the B3LYP/LANL2DZ technique to review the digital and structural traits of Graphene Oxide (GrO) mixed with ZnO, Fe₂O₃, and Al₂O₃. The analysis examines how GrO anchoring websites, together with hydroxyl (-OH), epoxy (-O), and carboxyl (-COOH) teams, have an effect on the efficiency of those composite supplies. The outcomes present that the hydroxyl web site creates the most important conductivity enchancment as a result of it decreases the vitality hole of GrO from 2.7606 eV to 0.3894 eV within the iron oxide hybrid. The Whole Dipole Moments (TDM) of molecules with epoxy (O) interactions attain 8.7375 Debye, which signifies that these molecules have larger chemical sensing sensitivity. For learning the floor and stability of the mannequin molecules, each the Molecular Electrostatic Potential, MESP, and QTAIM are calculated. Each portions are thought of advanced and web site -dependent digital conduct; making use of these calculations can certainly tune the digital construction by selecting particular practical teams. The analysis demonstrates that the bodily integration of metallic oxides with graphene oxide leads to the formation of a composite materials with enhanced properties, because the experimental information (confirmed by spectroscopic and microscopic analyses) align with the theoretical predictions derived from computational modeling. Outcomes devoted the studied fashions and/or supplies for sensors and electrodes, in addition to for catalytic work.
