Facile controlled synthesis of core–shell/yolk–shell/hollow ZIF-67@Co-LDH/SiO₂via a self-template method

Abstract

Through the protection effect of CTAB, a facile controlled synthesis of core–shell/yolk–shell/hollow ZIF-67@Co-LDH/SiO2 under ambient conditions by adjusting the reaction time was realized.

Nanovoid-Enhanced Thin-Film Composite Reverse Osmosis Membranes Using ZIF-67 Nanoparticles as a Sacrificial Template

“…XRD was also employed to reveal the crystalline structure. All the characteristic diffraction peaks as shown in Figure d agree well with the literature . In short, the ZIF-67 nanoparticles possess a typical rhombic dodecahedral morphology with a narrow size distribution and an average size of about 31.6 nm.…”

“…All the characteristic diffraction peaks as shown in Figure 2d agree well with the literature. 44 In short, the ZIF-67 nanoparticles possess a typical rhombic dodecahedral morphology with a narrow size distribution and an average size of about 31.6 nm. Moreover, the UV−Vis spectra were recorded as a function of time to assess the instability of ZIF-67 in water as shown in Figure 2c.…”

“…After 6 h, the characteristic peak almost vanishes, indicating that a duration of 6 h is sufficient for complete self-degradation of ZIF-67. Meanwhile, a new peak at around 630 nm arises, attributed to the hydrolysis of cobalt ions and formation of cobalt hydroxides. , …”

Preparation of Bimetallic CuZn@mSiO2 Yolk‐Shell Catalyst for the Selective Oxidation of Cumene to Acetophenone

“…YSN structure is assembled with multifunctional cores and permeable shells via precise construction. [14] Movable cores provide more exposed active sites prompting effective interaction of guest molecules. The outer shell prevents agglomeration of adjacent nanoparticles, and the short channels through the shell conduce rapid diffusion of reactants.…”

Amorphous Yolk–Shelled ZIF-67@Co3(PO4)2 as Nonprecious Bifunctional Catalysts for Boosting Overall Water Splitting

“…However, poor electrical conductivity and narrow micropores represent significant drawbacks. , The construction of yolk–shell/hollow electrode materials from MOFs by rational design has emerged as a useful approach in recent years, − thus providing a solution for the drawbacks associated with ZIF-67. Complex yolk–shell/hollow structures are of significant interest owing to their unique properties, such as low density, controllable shape, high loading capacity, microreactor environment, high mass/energy transmission, and effective nanoparticle distribution benefiting from the large specific surface area. ,− Furthermore, they are also able to effectively improve the conductivity by shortening the diffusion path due to their mesoporous structures.…”
