In this study, we synthesized two nanocomposites, cross-linked PVA/HKUST and PVA/ZIF-67, by integrating metal–organic frameworks (MOFs) into electrospun polyvinyl alcohol (PVA). Several characterization techniques including FTIR, XRD, ICP, SEM, TGA, UV–Vis, zeta potential, N2 adsorption–desorption were employed. The adsorption performance of the composites for cefixime (CFX) removal was assessed under varying conditions such as MOF content, contact time, pH, initial CFX concentration,...
Abstract Latent cooling load accounts for 30% of the total air-conditioning, and its proportion is even higher in many tropical subtropical climates. Traditional vapour-compression air-conditioning (VCAC) has a low coefficient performance (COP) due to refrigeration dehumidification process, which often makes necessary great deal subsequent re-heating. Technologies using conventional desiccants or sorbents indoor moisture control are less competitive than VCAC their high regeneration...
An imidazolium-based ionic liquid was embedded into MIL-101(Cr) via coordinate and covalent bonds to synthesize heterogeneous catalysts for efficient CO2 capture at low pressure fixation with epoxides. In MIL-IL(A), the coordinated Cr centers, while in MIL-IL(B), attached a bond. These two materials were used p/p0 = 0.033 0 °C. The results showed that absorbing capacity MIL-IL(A) MIL-IL(B) is 5.46 7.84 times higher than of parent MOF, respectively. loading measured by IC, CHN,...
Biodiesel presents a sustainable alternative to fossil fuels, yet traditional homogeneous catalysts like sodium and potassium hydroxide face challenges with separation reuse. Calcium oxide (CaO) is an effective heterogeneous catalyst for biodiesel production, but its chemical instability under reaction conditions restricts long-term performance. This study introduces MOF-mediated synthesis (MOFMS) of catalysts, specifically CaO@ZnO ZnO@CaO nanocomposites, from inexpensive non-toxic metal...
Hierarchical H-form ZSM-5 (h-ZSM-5) was synthesized and successfully functionalized with imidazolium-based ionic liquids for solvent-free insertion of carbon dioxide to epoxides synthesis cyclic carbonate. Tetrapropyl ammonium hydroxide polyurethane foam were used as soft hard templates, respectively, introduce mesoporosity in the structure. The hierarchical provided a large surface area covalent attachment produce h-ZSM-5-IL. successful new catalyst confirmed by X-ray diffraction, Fourier...
There is a growing concern that the increasing concentration of CO2 in atmosphere contributes to potential negative impact on global climate change.
