This article, we present a thorough and straightforward hydrothermal method towards the production of reduced graphene oxide templated MIL-53(Fe) hybrids RGO@MIL-53(Fe). The structural characteristics of created hybrids were identified by using BET, FESEM, powder X-ray diffraction, and FTIR techniques. Methylene blue (MB) dye (a model water pollutant) was used to evaluate H2O2-assisted photo-catalytic efficiency of RGO@MIL-53(Fe).

This study focuses on examining the effect of the π bridge on the properties of the molecule. The structural parameters of the molecular geometry were optimized, the HOMO and LUMO energies were calculated and analyzed in detail. In addition, the absorption wavelength, excitation energy, vibration intensity and electron transfer were calculated through the time-dependent density functional theory (TD-DFT) method.
