摘要： A heterogeneous material (e.g., a metal-organic framework or “MOF”) is useful for removing heavy metals from a liquid (e.g., water). The heterogeneous material may incorporate a group 16-containing heterocycle supported on solid media. Thiophene-containing MOFs, such as ATF-1 and DUT-67, may be used to remove lead from water. It is postulated that the metal is adsorbed via non-covalent interactions. The systems and methods described herein may also be applicable to other heavy metals. Thus, the applications are not limited to drinking water purification. Instead, the systems and methods may be used for a broad variety of other applications, such as nuclear waste remediation.

摘要： A method to form a phase change material (PCM). The method includes preparing a polymer solution by mixing an amount of a polymer in a solvent and mixing the polymer solution with an UiO-66 metal-organic framework (MOF) to form a composite. The polymer is a polyethylene glycol (PEG). The method further includes subjecting the composite to ultrasonic agitation and evaporating the solvent from the composite to form the PCM. After the evaporation of the solvent, particles of the PCM exhibit rounded octahedral structures.

摘要： Disclosed are a zirconium-based metal-organic framework material and a preparation method thereof. Plasma-activated water or strong acid electrolyzed water is added to a raw material system for preparing a zirconium-based metal-organic framework material UiO-66, and they are then subjected to a reaction to obtain a crude product. The crude product is subjected to a post-treatment to obtain the zirconium-based metal-organic framework material UiO-66.
