2020年2月1日 · ZIF-11 derived nanoporous carbons were prepared by a one-step calcination. The synthesized Z11-900 displayed a superior iodine vapour affinity of 3775 mg/g. Z11-900 achieved an excellent regeneration efficiency for iodine vapour uptake.

2019年2月1日 · Optimum parameters for obtaining highly crystalline, pure-phase ZIF-11 are given. The synthesis of ZIF-11 in N, N-Diethylformamide (DEF) at varying reaction temperatures, times and different molar compositions of the reaction mixture was investigated in detail in order to identify ranges of the formation of phase-pure ZIF-11.

2021年7月12日 · Herein, we report a systematic study on the synthesis of ZIF-11 as a supported membrane. For this, we adapted optimized conditions for the ZIF-11 powder synthesis, identified in our previous works, to form ZIF layers on symmetric and asymmetric stainless-steel and asymmetric ?-Al2O3 supports.

2020年7月26日 · Facile synthesis of metal–organic framework based on zeolitic imidazolate (ZIF-11) has been optimized to get a material with rho topology. For the first time AgNPs in various dosing amounts (using 150, 300 and 500 μL of its suspension in methanol) have been successfully encapsulated within ZIF-11 matrix at room temperature using binary ...

2023年2月15日 · The ZIF-11@ZIF-8 core–shell structure experienced a 4.6-fold increment in BET specific surface area compared to the pristine ZIF-11 MOF. Gas adsorption isotherms of CO 2, N 2, CH 4, C 2 H 4, and C 2 H 6 were acquired at two different temperatures of 298 and 328 K, and equilibrium pressures up to 4 bar.

We demonstrate the synthesis of zeolitic imidazolate framework ZIF-11 via a microwave assisted approach. The resultant 2–7 μm crystals were synthesized in minutes and displayed BET surface areas as high as 745 m2 g−1.

ZIF-11和AgNPs @ ZIF-11复合材料在空气和N 2 下高达500°C的温度下都非常稳定 大气层。已经发现，AZ1复合材料在pH≥8时对MB（1.6 mg / L）表现出优异的光催化活性（几乎100％降解）。

在本文中，溶剂辅助接头交换（SALE）技术成功应用于多孔ZIF-11@ZIF-8核壳复合结构金属有机骨架（MOF）的合成。 RHO 型 ZIF-11 由于具有更大的空腔以及更高的接头旋转自由度，因此充当核心并有助于提高吸附能力。 另一方面，SOD 型 ZIF-8 具有较低的接头柔韧性，因此具有更强的分子筛分特性，从而提高了吸附选择性。 通过 XRD、FTIR、FESEM、EDS、TEM、BET 和 TGA 分析对制造的 MOF 的形态和结构进行了表征，并确认了核壳结构的形成。 合成的 ZIF …
