In the present study, a ternary magnetic nanocomposite (SiO2/MnFe2O4/ZIF-8) was synthesized via embedding of SiO2/MnFe2O4 within metal–organic framework (ZIF-8). The characterized using suitable techniques including FT-IR, XRD, SEM, TEM, VSM, and BET. showed high surface area (SBET = 831 m2·g−1) superparamagnetic behavior (23.7 emu·g−1). All characterization confirmed successful combination thr...

In this study, polymeric nanocomposites of zeolitic imidazolate frameworks (ZIFs) were synthesized by assembly a biomimetic polymer-polydopamine (PDA)onto halloysite nanotubes (HNTs@PDA), followed the in situ growth framework-8 (ZIF-8) on surface HNTs@PDA. The obtained (HNTs@PDA/ZIF-8) prevented agglomeration ZIFs and increased number active sites derived from PDA. factors influencing heavy met...

Ionic liquids (ILs) show promise as safe electrolytes for electrochemical devices. However, the conductivity of ILs decreases markedly at low temperatures because of strong interactions arising between the component ions. Metal-organic frameworks (MOFs) are appropriate microporous host materials that can control the dynamics of ILs via the nanosizing of ILs and tunable interactions of MOFs with...

The core-shell hybrid structure is the simplest motif of two-component systems which consists of an inner core coated by an outer shell. Core-shell composite materials are attractive for their biomedical, electronic and catalytic applications in which interface between core and shell is critical for various functionalities. However, it is still challenging to study the exact role that interface...

Porous membranes with ultrafast ion permeation and high ion selectivity are highly desirable for efficient mineral separation, water purification, and energy conversion, but it is still a huge challenge to efficiently separate monatomic ions of the same valence and similar sizes using synthetic membranes. We report metal organic framework (MOF) membranes, including ZIF-8 and UiO-66 membranes wi...

Novel honeycomb-like mesoporous aluminum hydroxide (pATH) was synthesized via a facile one-step reaction by employing ZIF-8 as a template. This self-decomposing template was removed automatically under acidic conditions without the need for any tedious or hazardous procedures. Meanwhile, the pore size of pATH was easily modulated by tuning the dimensions of the ZIF-8 polyhedrons. Of paramount i...

The rational design and facile fabrication of cost-effective, efficient, robust non-precious metal-based carbon nanomaterials are great significance. Herein, under the control temperature, single-crystal-to-single-crystal transformation from MOF-5 to ZIF-8 via ligand exchange can be easily achieved with intermediate final structures ZIF-8-M ZIF-8-F, respectively. After pyrolysis Fe-doped MOF (m...

A wound evolves with variable pHs depending on the healing stage, and maintenance of mild acidic condition can help by deterring formation a biofilm. Herein, dual-layer dressing an acid-responsive zeolitic imidazolate framework–8 (ZIF-8) layer acid-modulating is designed to control acid-dependent release therapeutic agents for improved process. The outer coated curcumin-incorporated ZIF-8, wher...

Nanoporous carbons with high surface area are achieved through direct carbonization of a commercially available zeolitic imidazolate framework (ZIF-8) without any additional carbon sources. The resultant nanoporous carbons exhibit high electrochemical capacitances in an acidic aqueous electrolyte.
