Abstract

The aim of this study was to evaluate and compare the effectiveness of the combination of silver nanoparticles (Ag NPs) and two metal oxides (Fe₂O₃ and CoO) for the removal of methylene blue (MB) molecules from aqueous solutions. To achieve this purpose, Silver (Ag) nanoparticles were successfully deposited onto metal oxides (Fe₂O₃ and CoO) nanocomposites, which were employed as adsorbents and photocatalysts. The prepared photocatalysts (Ag/Fe₂O₃ and Ag/CoO) were used for the absorption of methylene blue, an organic pollutant. Various analytical techniques such as Field Emission Scanning Electron Microscope (FESEM), Energy Dispersive X-ray (EDX), and Powder X-ray diffraction (XRD) were used to characterize the prepared nanomaterials. The results of the energy dispersive X-ray analysis identified the presence of the elements (Ag, Fe, and Co) and their distribution on the surface of the material. The X-ray diffraction pattern also confirmed the formation of nanocomposites (Ag/Fe₂O₃ and Ag/CoO). The degradation of MB in the presence of sunlight ratified that the nanocomposites (Ag/Fe₂O₃ and Ag/CoO) had weak photocatalytic absorption efficiency controlled by pseudo-second order kinetic model. Comparing both nanocomposites, the nanocomposite (Ag/Fe₂O₃) showed the best photocatalytic performance with a percentage of 56% within 3h. The results of the photocatalytic experiments indicated that the introduction of Ag into the metal oxides limited the charge recombination process between the photogenerated electrons/holes and thus facilitated the absorption of methylene blue.
