Metal organic frameworks (MOFs) are topical crystalline materials with high porosity and inner surface areas synthesized from naturally occurring minerals. Such MOFs transition metals have attracted considerable attention because of their fascinating morphological diversity tunable characteristics. The coronene-based structural metal atoms by repeating a fixed coronene unit at several levels. In this study, topological indices NMR ESR spectral patterns computed for these to shed light on structures properties. We obtained mathematical expressions based degree degree-sum values the rectangular, hexagonal, parallelogram peripheral shapes. Furthermore, entropy measures novel evaluated help index functionals compared wide range degree-based descriptors. been distance vector sequences symmetries three MOFs.

Water contamination by heavy metals due to various anthropogenic activities has grown be a serious global issue that needs addressed ensure effective remediation. Recently, Metal-Organic Frameworks (MOFs), class of porous materials, have emerged as promising candidates for removal. In this study, we synthesized and evaluated novel 1,3,5-benzene tricarboxylic acid (BTC)-based metal-organic framework (UIO-66-BTC(Zr)) its ability adsorb metal Pb(II) from wastewater. X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FT-IR), photoelectron (XPS) characterization methods were used demonstrate the synthesis UIO-66-BTC(Zr). The proposed mechanisms binding UIO-66-BTC(Zr) identified chelation/coordination, pore filling, electrostatic interaction steps. According our findings, remarkable adsorption capacity 881.35 mg/g exhibits significant selectivity ions in solution over Cd(II), Cu(II), Zn(II), Ni(II) ions. Additionally, crystal structure adsorbed MOF remained stable, performance consistent five cycles, signifying potential sustainable efficient adsorbent removing real-world effluents. findings study open up prospects application new removal hazardous contaminants industrial Moreover, research serves crucial basis advancing studies on cost-effective environmentally friendly modification/synthesis upscaling production wider
