Impact of Swift Heavy Ion (SHI) irradiation is an effective way to tailor the properties of materials to enhance their applicability toward high-end applications. In the present investigation, hydrothermally synthesized Fe-BTC metal–organic frameworks (MOFs) were irradiated with ¹⁹⁷Au⁸⁺ ion beam, 100 MeV at fluence range of 1 × 10¹¹ ions/cm² and 1 × 10¹² ions/cm². Hydrothermally synthesized Fe-BTC MOFs were characterized by X-ray diffractometer, UV-Visible spectroscopy, Fourier-transform infrared spectroscopy (FTIR), Scanning electron microscope (SEM), Raman spectroscopy, and Atomic Force Microscopy (AFM). The significant modifications were observed as ion fluence increases, viz. decrease of crystallite size, increase of energy bandgap, reduction in average surface roughness, and the formation of new functional group (C–H) at a higher fluences 1 × 10¹² ions/cm².

Swift 重离子 (SHI) 辐照的影响是定制材料特性以增强其对高端应用的适用性的有效方法。在本研究中，水热合成的 Fe-BTC 金属有机骨架 (MOF) 用¹⁹⁷ Au ⁸⁺离子束、100 MeV 以 1 × 10 ¹¹ 离子/cm ²和 1 × 10 ¹² 离子/cm ^{2 的}通量范围照射. 通过X射线衍射仪，紫外可见光谱，傅立叶变换红外光谱（FTIR），扫描电子显微镜（SEM），拉曼光谱和原子力显微镜（AFM）对水热合成的Fe-BTC MOF进行了表征。随着离子注量的增加，观察到显着的改变，即。晶粒尺寸减小，能带隙增加，平均表面粗糙度降低，以及在更高的通量 1 × 10 ¹² 离子/cm ^{2 下}形成新的官能团 (C-H) 。
