2022年1月1日 · The result clearly revealed that ZIF-67 derived NiCo LDH with optimized particle size, denoted as 0.15 M CTAB, had the highest ECSA value (3.52 mF/cm 2), indicating that NiCo LDH derived from ZIF-67 with optimized particle size may not only retain the 3D hierarchical structure, but also provide more specific surface area to further boost the ...

2021年6月15日 · Co LDH, ZIF-9(III)/Co LDH, and ZIF-9(III) were then obtained through a gentle reaction between ZIF-9(I) and Co(NO 3) 2 ·6H 2 O in the water–ethanol solution. During the chemical transformation process, the solvent composition played an imperative role in controlling the components of the final products.

2018年2月10日 · In details, ZIF-8 was measured at 35–900 °C under N 2 flow with a heating rate of 5 °C min −1 and samples of ZIF-8-C, NiAl LDH and ZIF-8-C@NiAl LDH composite were measured at 35–800 °C under air atmosphere with a heating rate of 5 °C min −1. X-ray diffraction (XRD) patterns were measured with D/max-TTRIII.

2023年6月19日 · A novel sorbent ZIF-67/LDH@C was synthesised using mild etching and co-precipitation and carbonization calcination for the elimination of lead ions (Pb 2+), malachite green (MG), and congo red (CR) from water.The three-dimensional hollow MOF structure and two-dimensional LDH nanosized layers of ZIF-67/LDH@C were demonstrated by scanning electron microscope (SEM), transmission electron ...

2024年7月10日 · Herein, the NiCo-LDH nanosheets derived from ZIF-67 were in situ grown on the surface of a basic copper cobalt carbonate (CoCu) urchin-like skeleton and supported by nickel foam (CoCu@NiCo-LDH). The well-designed three-dimensional (3D) hierarchical nanostructure not only effectively prevents the aggregation of NiCo-LDH nanosheets, but also ...

2023年3月27日 · The Zif-67@NiCo-LDH simultaneously inherited the cycling stability of Zif-67 and the high capacity of NiCo-LDH, which effectively improves the conductivity and structural integrity under the synergistic effect of the flower-shaped heterostructures and compositions and showed a good electrochemical performance. This work might enable the future ...

2023年12月27日 · ZIF-67-Derived Antivirus Cobalt Hydroxide LDH Nanosheets Produced through High-Concentration Cobalt Ion-Assisted Hydration. Ben Wu, Ben Wu. ... due to the matching of the hydrolysis rate of ZIF-67 and in situ growth rate of cobalt hydroxide orchestrated by high concentration of cobalt ions. Notably, the CHN contains a higher proportion of ...

2020年11月25日 · The morphology of Co-LDH@ZIF-67 was examined by scanning electron microscopy (SEM) (Figure 1a,b; Figure S1, Supporting Information).Co-LDH@ZIF-67 has a cubic morphology and is highly monodisperse, with a particle size of 350 nm (Figure 1a).High-magnification SEM (Figure 1b) shows that Co-LDH@ZIF-67 has a hollow structure and Co-LDH is encapsulated in this structure.

ZnAl-LDH@ZIF-8杂化物表现出显着的光催化CO 2转化率为9.03 μmol·g -1 ·h -197.77%的高选择性。此外，研究了ZnAl-LDH和ZIF-8相互作用对光电荷激发转移和光催化CO产生的影响，阐明了催化剂组成、表面结构、光电性能和催化性能之间的关系。
