Photocatalytic pollutant degradation and water purification using a photocatalyst based on MIL-۱۰۰ (Fe,Co) metal-organic framework

MIL-۱۰۰ (Fe, Co) is a type of Metal-Organic Framework (MOF) known for its large surface area and well-defined porosity, which is advantageous for adsorption and catalytic applications. This high surface area is often achieved through the interconnected network of metal nodes and organic linkers. MOF MIL-۱۰۰ (Fe, Co) structures can be tuned to have specific pore sizes and shapes by varying the choice of metal nodes and organic linkers during synthesis. This tunability allows for selective adsorption of molecules based on their size and chemical properties. Due to its porous structure, MOF MIL-۱۰۰ (Fe, Co) is effective in adsorbing gases, liquids, and pollutants from various environments. It can be utilized as photocatalyst in environmental applications such as gas storage, gas separation, and removal of organic pollutants from water. Additionally, Carbon nitride (C۳N۴), specifically graphitic carbon nitride (g-C۳N۴), is a promising material for environmental applications due to its unique properties that facilitate both adsorption and photocatalytic degradation of pollutants. C۳N۴ materials, especially g-C۳N۴, have a layered structure with a high surface area and abundant surface defects. This structure provides active sites for physical adsorption of pollutants such as organic dyes and contaminants from water. In this case, nanocomposites combining carbon nitride (C۳N۴) and Metal-Organic Framework MIL-۱۰۰ (Fe,Co) present a promising approach for photocatalytic applications in environmental pollution removal. This study investigates the synthesis, characterization, and photocatalytic performance of g-C۳N۴/MIL-۱۰۰ (Fe,Co) nanocomposites under UV light irradiation. C۳N۴, known for its semiconductor properties and MIL-۱۰۰ (Fe,Co), renowned for its high surface area and metal centers, were integrated to harness synergistic effects in pollutant degradation. The nanocomposites were synthesized via a facile method and characterized using X-ray diffraction (XRD) and UV-VIS analysis. Photocatalytic activities were evaluated by monitoring the degradation of organic pollutants in aqueous solutions. Results demonstrated that the g-C۳N۴/MIL-۱۰۰ (Fe,Co) nanocomposites exhibited enhanced photocatalytic efficiency compared to individual components, attributed to improved charge separation, extended light absorption range, and increased active sites for pollutant adsorption. The optimized nanocomposites showed excellent stability and reusability, highlighting their potential for sustainable environmental remediation.
