“…The calculated specific surface area is 5.026 m 2 /g. The adsorption curve is depicted as a type IV curve confirming the presence of mesopores [50–52] . This mesopore formation confirmed with the pore size distribution curve shown in Figure 2B, which reveal the BJH pore size is 3.78 nm and pore volume is 0.045 cm 3 /g.…”

The development of bimetallic and magnetic nanomaterials as a catalyst is highly desirable for organic transformations due to their recyclability for the sustainable future of chemical industries. Bimetallic CoNi nanoflowers were developed via the facile liquid‐phase reduction method and were employed for the hydrogenation of terminal alkynes. The structural and morphological studies were analyzed by X‐ray diffraction, Field‐Emission Scanning Electron Microscopy, and High Resolution Transmission Electron Microscopy. The bimetallic CoNi nanoflower exhibited 100 % conversion with ∼100 % selectivity towards alkane products with recyclability up to six cycles. The transfer hydrogenation mechanism was proposed via diimide formation with Co(0)/Ni(0) state, confirmed by X‐ray Photoemission Spectroscopy analysis.

“…The result revealed that the UiO-66 colloidal particles with the smallest size and more missing linkers exhibited the best performance (Figure 17d). Li et al [170] synthesized MIL-125 MOF particles with different sizes and investigated their catalytic activity on oxidative desulfurization reaction of dibenzothiophene (DBT) and 4,6-dimethyldibenzothiophene (4,6-DMDBT) (Figure 17e-h). It was found that 50 nm MIL-125 particles have higher catalytic performance than those micrometer-sized particles (Figure 17i,j), possibly because the nanosized MOF particles had a larger external surface area, resulting in more accessible active sites.…”

Metal‐Organic Framework‐Based Colloidal Particle Synthesis, Assembly, and Application

Metal-organic frameworks (MOFs) assembled from metal nodes and organic ligands have received significant attention over the past two decades for their fascinating porous properties and broad applications. Colloidal MOFs (CMOFs) not only inherit the intrinsic properties of MOFs, but can also serve as building blocks for self-assembly to make functional materials. Compared to bulk MOFs, the colloidal size of CMOFs facilitates further manipulation of CMOF particles in a single or collective state in a liquid medium. The resulting crystalline order obtained by self-assembly in position and orientation can effectively improve performance. In this review, we summarize the latest developments of CMOFs in synthesis strategies, selfassembly methods, and related applications. Finally, we discuss future challenges and opportunities of CMOFs in synthesis and assembly, by which we hope that CMOFs can be further developed into new areas for a wider range of applications.[a] Q.

Venturello‐structured polyoxometalates (POMs) are effective homogeneous catalysts and confining POMs to size‐matched metal‐organic frameworks (MOFs) as heterogeneous catalyst is an effective way to improve their practical application. The appropriate pore and narrow window of pristine UiO‐67 can not only enclose POMs in single molecule but also limit their leaching and can provide a suitable platform for the oxidation of most sulfur‐containing organic compound. The composite (CTA)3PW4@UiO‐67 was prepared by a facile in situ synthesis method, characterized by a variety of means and tested for desulfurization of multicomponent simulated diesel. The results prove that the active component (CTA)3PW4 is effectively encapsulated, and the composite (CTA)3PW4@UiO‐67 show remarkable desulfurization activity and excellent reusability. In addition, the kinetics and possible mechanism of the reaction were investigated. This work opens up a new idea for the design of “host‐guest adapted” catalyst suitable for fuel desulfurization technology.
