Lithium-selenium battery is nowadays a highly competing technology to the commercial Li-ion because it has high volumetric capacity of 3253 mAh cm-3 and gravimetric 675 g-1. However, practical application lithium-selenium (Li-Se) batteries impeded by shuttle effect soluble polyselenides during cycling process. Herein, we report in situ growth pyrolysis metal-organic framework zeolitic imidazola...

Zn1?xCdxS catalysts with Zeolitic Imidazolate Framework-8 (ZIF-8) as the precursor were successfully prepared by ion exchange method, and ability electrochemical properties of a series ZIF-8, ZnS in photocatalytic degradation 2-CP TC investigated. Doping Cd ions was able to modulate band gap width improve utilization visible light photocatalyst. The nanocage hollow structure have better respons...

• Defect-free ZIF-8/GO/PIM-1 thin-film nanocomposite (TFN) membranes were fabricated. 2D ZIF/GO was produced by in situ growth of ZIF-8 on GO sheets as a continuous, uniform and thin layer. ZIF-8/GO composite results high dispersity compatibility ZG within PIM-1. PIM-1 infiltration into PVDF substrate avoided water pre-impregnation. TFN display PSI (228 kg m −2 h −1 ). In this work, film super-...

The fracture mechanism of zeolitic imidazolate framework (ZIF) glasses is revealed to be associated with bond switching organic linkers around central Zn nodes. more pronounced for ZIF smaller linkers.

The production of 1-butene by ethylene dimerization is an important chemical industrial process currently implemented using homogeneous catalysts. Here, we describe a highly active heterogeneous catalyst (Ni-ZIF-8) for dimerization, which consists isolating Ni-active sites selectively located on the crystal surface zeolitic imidazolate framework. Ni-ZIF-8 can be easily prepared simple one-pot s...

The CO2 capture performance of four zeolitic imidazolate frameworks (ZIFs), ZIF-10, ZIF-71, ZIF-68 and ZIF-69, was investigated in the presence of SO2 using molecular simulations. Our results show that SO2 is preferentially adsorbed over CO2. However, it also shows a cooperative effect on CO2 adsorption. In ZIF-10 and ZIF-71, the SO2 presence was found to have almost no effect on CO2 adsorption...

To enable the reuse of carbon dioxide (CO2), electrocatalytic reduction CO2 (CO2RR) into syngas with a controllable H2/CO ratio is considered cost-effective and intriguing approach. Here, number silver (Ag)-doped, zeolitic imidazole framework composites were prepared by facile method. The outcomes demonstrate that electroreduction on Ag-doped ZIF-8 catalysts produces just CO H2, without having ...

The nanoporous carbon fiber materials derived from electrospun polyacrylonitrile (PAN) fibers doped with zeolitic imidazolate framework are developed here and applied in the microbe fuel cell anode for enhanced interfacial electron transfer. Zeolitic fram-8 (ZIF-8) could introduce a large number of mesopores into fibers, which significantly promote indirect transfer mediated by flavins (IET). M...
