“…The peak at 1586 cm −1 is due to the CN stretching and complex bands from 1350 to 1500 cm −1 are due to the imidazole ring stretching. 45,46 Finally, a strong band at 421 cm −1 was observed during ZIF-8 formation 22 corresponding to the Zn–N stretching due to the bonding of zinc atoms in the ZIF-8 structure to the nitrogen atoms of the 2-MeIm linker.…”

Due to rapid socioeconomic development, increased phosphorus concentrations can cause eutrophication of water bodies, with devastating effects on environmental sustainability and aquatic ecosystems. In this study, ZIF-8-PhIm was prepared for phosphorus removal using 2-phenylimidazole via the solvent-assisted ligand exchange (SALE) method. The structure and composition of ZIF-8-PhIm were characterized by various methods, including X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FT-IR), 1 H nuclear magnetic resonance (NMR), X-ray photoelectron spectroscopy (XPS), and Brunauer−Emmett−Teller (BET) analysis. Compared to the ZIF-8 material, it exhibited a multistage pore structure with larger pore capacity and pore size, increased hydrophilicity, exposure of more adsorption sites, and also stronger electrostatic interaction. Under optimized conditions (T = 298 K, C 0 = 150 mg/L, dose = 0.2 g/ L), the adsorption capacity of ZIF-8-PhIm reached 162.93 mg/g, which was greater than that of the ZIF-8 material (92.07 mg/g). The Langmuir isotherm and pseudo-second-order kinetic models were suitable for describing the phosphate adsorption of ZIF-8-PhIm. The main effects of ZIF-8-PhIm on phosphate adsorption were Zn−O−P bonding and electrostatic interactions. It also had good regeneration properties. The ZIF-8-PhIm/CS spheres were prepared using chitosan (CS) as the cross-linking agent. The results of dynamic adsorption experiments on the spheres showed a saturation capacity of 85.69 mg/g and a half-penetration time of 514.15 min at 318 K according to the fitted results.

“…However, synthesizing MOFs is a major process for the industry to scale up from lab to pilot scale production. With this concern, the various synthesis methodologies for the synthesis of MOFs including solvothermal, hydrothermal, [ 36 ] mechanochemical, [ 37 ] dry gel conversion, [ 38 ] microfluidics, [ 39 ] microwave‐assisted, [ 40 ] and ultrasound [ 24,41 ] have been reported.…”

Sonochemical Approach of Highly Thermal, Mechanical, and Corrosion Inhibition Performance of Metal–Organic Framework (ZIF‐8)‐Decorated Waterborne Polyurethane Nanocomposite

Herein, highly porous metal-organic framework (ZIF-8)-decorated environmental friendly waterborne polyurethane (WPU) (ZIF-8@WPU) nanocomposites via facile sonochemical technique are synthesized. The ZIF-8@WPU shows threefold excellent mechanical performance (tensile strength %23 MPa and elongation 670%) at a very low 2.5 wt% filler loading compared to pristine WPU. In addition, the synthesized ZIF-8@WPU exhibits high thermal stability and water vapor permeability properties with increasing nanofiller concentration. Interestingly, the incorporation of ZIF-8 into WPU potentially improves the corrosion inhibition performance with a superior corrosion rate ( υ corr) 1.7 Â 10 À2 mm year À1 and %94% protection efficiency (PE) at lower filler (2.5 wt%) loading, attributing to the facile synthesis methods, internal structural arrangement, well interaction of filler and matrix, high surface area, and tuneable pore size of filler material. The crystallinity of ZIF-8 and ZIF-8@WPU is analyzed by powder X-ray diffraction, morphology by scanning electron microscopy, thermal properties by thermogravimetric analysis, and mechanical properties by the universal testing machine. This new insight has potential toward the green approach for synthesizing and structural engineering high-performance advanced nanocomposites in the coating, breathable devices, and food packaging industrial utilization.
