Groundwater contamination by organic pollutants like methyl orange (MO) presents serious environmental challenges, highlighting the need for effective degradation solutions. In this study, we investigate a hybrid Ti₃C₂ MXene/Fe-N-C catalyst for degrading MO under visible light. We synthesized and characterized the catalyst to uncover its structural, surface, and chemical properties, which are crucial for its catalytic performance. X-ray Diffraction (XRD) confirmed the catalyst’s crystalline structure, while Brunauer–Emmett–Teller (BET) surface area analysis showed a substantial surface area of 350 m2/g, enhancing its adsorption capabilities. X-ray Photoelectron Spectroscopy (XPS) revealed the presence of Fe 2p and N 1s peaks, indicating the incorporation of iron and nitrogen functional groups that are key to generating reactive oxygen species. Under optimized conditions, the catalyst achieved a remarkable 99.5% degradation of MO in just 80 min at pH 5. These results highlight the Ti₃C₂ MXene/Fe-N-C hybrid catalyst as a highly effective and sustainable option for groundwater remediation.

摘要

Groundwater contamination by organic pollutants like methyl orange (MO) presents serious environmental challenges, highlighting the need for effective degradation solutions. In this study, we investigate a hybrid Ti₃C₂ MXene/Fe-N-C catalyst for degrading MO under visible light. We synthesized and characterized the catalyst to uncover its structural, surface, and chemical properties, which are crucial for its catalytic performance. X-ray Diffraction (XRD) confirmed the catalyst’s crystalline structure, while Brunauer–Emmett–Teller (BET) surface area analysis showed a substantial surface area of 350 m2/g, enhancing its adsorption capabilities. X-ray Photoelectron Spectroscopy (XPS) revealed the presence of Fe 2p and N 1s peaks, indicating the incorporation of iron and nitrogen functional groups that are key to generating reactive oxygen species. Under optimized conditions, the catalyst achieved a remarkable 99.5% degradation of MO in just 80 min at pH 5. These results highlight the Ti₃C₂ MXene/Fe-N-C hybrid catalyst as a highly effective and sustainable option for groundwater remediation.
