In this study, zeolitic imidazolate framework (ZIF-67) derived nano-porous carbon structures that were further hybridized with MnO2 tested for oxygen reduction reaction (ORR) as cathode material fuel cells. The prepared electrocatalyst was characterized by X-ray powder diffraction (XRD), scanning electron microscopy (SEM) and Energy Dispersive Analysis (EDX). Cyclic voltammetry performed on the...

The lithium-sulfur (Li-S) battery has been attracting much more attention in recent years due to its high theoretical capacity and low cost, although various issues, such as the “shuttle effect” use ratio of active materials, have hindering development application Li-S batteries. separator is an important part batteries, modification a simple effective strategy improve electrochemical performan...

Cobalt-based electrocatalysts have been considered promising materials for the oxygen evolution reaction (OER). Herein, we now report synthesis of vanadium-doped CoS/Co9S8 heterostructures embedded on carbon nanorods (V-CoS/Co9S8@CNR), which was realized through one-step sulfurization Zeolitic Imidazolate Framework-67 (ZIF-67) grown V2O5 (V2O5@ZIF-67). The results experiment and theoretical cal...

Split-ring resonators are excellent left-handed metamaterials for significant electromagnetic coupling behavior. In this work, a split-ring resonator prepared with Ni-doped zeolitic imidazolate framework-67/epoxy resin (ZIF-67/ER) was embedded in the top layer to optimize microwave absorption efficiency 2–4 GHz frequency band. The ZIF-67/epoxy served as bottom improve 4–8 Honeycomb conductive c...

Carbon-carbon heterostructures are an emerging material paradigm to promote the development of capacitive deionization (CDI). The synthesis this heterostructure with designed functionalities derived from metal-organic frameworks (MOFs) is interesting, but it has always been challenging. We develop MOF-on-MOF nanoarchitectures obtain a selectively functionalized nitrogen-doped carbon@graphitic c...

Because of the high separation performance and easy preparation, mixed-matrix membranes (MMMs) consisting of metal-organic frameworks have received much attention. In this article, we report a novel ZIF-300/PEBA MMM consisting of zeolite imidazolate framework (ZIF-300) crystals and polyether block amide (PEBA) matrix. The ZIF-300 crystal size was effectively reduced by optimizing the hydrotherm...
