Mechanically Synthesized Zirconium-based MOFs for Adsorptive Removal of Nerve Agent Simulants
Journal Title: Journal of Applied Material Science - Year 2025, Vol 1, Issue 1
Abstract
In this study, two zirconium-based metal-organic frameworks (Zr-MOFs), namely UiO-66 and NH2-UiO-66, were synthesized using a simple, fast, and eco-friendly solvent-assisted grinding (mechanochemically) approach. The purity and quality of prepared Zr-MOFs were fully characterized via powder X-ray diffraction (PXRD), Fourier transform infrared (FT-IR) spectroscopy, and N2 adsorption/desorption analyses. Due to its structural similarity to phosphorus nerve agents, dimethyl methylphosphonate (DMMP) was used in this study as the model nerve agent to evaluate the adsorption capacity of prepared Zr-MOFs toward nerve agents. Photoluminescence (PL) spectroscopy was employed to monitor the DMMP concentration during the removal process. Adsorption capacity values of 667 and 834 mg/g were obtained for UiO-66 and NH2-UiO-66, respectively, indicating their strong interaction with phosphorus nerve agents. Furthermore, the stability and recyclability of the absorbents after the absorption process were confirmed using FT-IR and PXRD results, confirming that Zr-MOFs are perfect candidates for applications related to chemical warfare protection.
