“…1500 nm, which was consistent with the morphology of UiO-67 reported in the literature [48,49]. During the process of crystallization, CTAB was adsorbed on the surface of the UiO-67 primary crystal, which would decrease the van der Waals force and surface energy, promoting the ordered agglomeration, thus forming a more regular morphology [50][51][52]. The long hydrocarbon chains of CTAB also repelled each other, preventing the further interaction with other UiO-67 crystals and excessive growth of UiO-67, resulting in a smaller particle size [53,54].…”

“…This may be owing to the fact that most CTAB existed as micelles, rather than dispersed forms, which did not interact well with surfaces [51,55]. Wang et al [52] also reported that the morphology and size of 146S@ZIF-8 can be changed by adding CTAB. Jubeer et al [56] reported that the particle size of ZnS could be adjusted by changing the concentration of CTAB.…”

A series of MOF-derived ZrO2-supported Pd-Ni bimetallic catalysts (PdNi/UiO-67-CTAB(n)-A500) were prepared by co-impregnation and pyrolysis at 500 °C under air atmosphere using UiO-67-CTAB(n) (CTAB: cetyltrimethylammonium bromide; n: the concentration of CTAB; n = 0, 3, 8, 13, 18) as a sacrificial template. The catalytic activity of PdNi/UiO-66-CTAB(n)-A500 in 1,3-butadiene hydrogenation was found to be dependent on the crystal morphology of the UiO-67 template. The highest activity was observed over the PdNi/UiO-67-CTAB(3)-A500 catalyst which was synthesized using UiO-67-CTAB(3) with uniform octahedral morphology as the template for the 1,3-butadiene selective hydrogenation. The 1,3-butadiene conversion and total butene selectivity were 98.4% and 44.8% at 40 °C within 1 h for the PdNi/UiO-67-CTAB(3)-A500 catalyst, respectively. The catalyst of PdNi/UiO-67-CTAB(3)-A500 can be regenerated in flowing N2 at 200 °C. Carbon deposited on the surface of the catalyst was the main reason for its deactivation. This work is valuable for the high-efficiency bimetallic catalyst’s development on the selective hydrogenation of 1,3-butadiene.

“…43 Strategies for the assisted synthesis, regulation, and control of multifunctional monolithic MOFs with surfactants such as polyvinylpyrrolidone (PVP), polyethylene glycol-400 (PEG-400), and cetyltrimethylammonium bromide (CTAB) have gained extensive research interest. 44 In 2018, Liu et al prepared ultrathin MOF nanosheets using a surfactant-assisted (PVP) method and then loaded them on flexible porous supports via vacuum filtration, finally producing flat ZnTCPP-MOF nanolayers for the separation of CO 2 (Figure 3), CO 2 transmittance ∼2100 GPU, and CO 2 /N 2 ideal selectivity ∼30. In summary, the as-prepared grooved layer of porous MOF nanosheets can significantly reduce the gas transport resistance, thereby maximizing the gas flux of the composite membrane.…”

Metal−organic frameworks (MOFs) have attracted considerable attention owing to their large surface area and high structural tunability, which lead to a wide range of applications. Owing to excellent properties of MOFs in various applications, the synthesis process of MOFs has been gradually developed with high yields and stable shapes to fulfill industrial requirements. However, the industrial usage of traditional powder-formed MOFs is limited because powder may lead to safety issues and disperse easily. Therefore, MOFs with different shapes and standard properties are required for applications. This review has summarized currently reported methods for shaping MOFs, e.g., binder-based, high-pressure, surfactant-assisted, supercritical CO 2 (scCO 2 ), and sol−gel processes. The industrial applications based on shaped MOFs are summarized to support future studies on the formation of MOFs with stable shapes.

“…The polar groups in His strengthened hydrogen bond formation with solvent water molecules, creating a hydrated shell on the Ad5@His-aZn-mIM surface, further enhancing its conformational stability at high temperatures ( Figure 2 f,g). Recently, Wang et al successfully synthesized crystalline ZIF-8 on foot-and-mouth disease virus by pre-lowering the pH of the 2-mIM solution to 9.0 [ 75 ]. The encapsulated viral vaccine induced approximately ten times higher antibody titers and significantly increased cellular immune responses in mice.…”

Living organisms in nature, such as magnetotactic bacteria and eggs, generate various organic–inorganic hybrid materials, providing unique functionalities. Inspired by such natural hybrid materials, researchers can reasonably integrate biomaterials with living organisms either internally or externally to enhance their inherent capabilities and generate new functionalities. Currently, the approaches to enhancing organismal function through biomaterial intervention have undergone rapid development, progressing from the cellular level to the subcellular or multicellular level. In this review, we will concentrate on three key strategies related to biomaterial-guided bioenhancement, including biointerface engineering, artificial organelles, and 3D multicellular immune niches. For biointerface engineering, excess of amino acid residues on the surfaces of cells or viruses enables the assembly of materials to form versatile artificial shells, facilitating vaccine engineering and biological camouflage. Artificial organelles refer to artificial subcellular reactors made of biomaterials that persist in the cytoplasm, which imparts cells with on-demand regulatory ability. Moreover, macroscale biomaterials with spatiotemporal regulation characters enable the local recruitment and aggregation of cells, denoting multicellular niche to enhance crosstalk between cells and antigens. Collectively, harnessing the programmable chemical and biological attributes of biomaterials for organismal function enhancement shows significant potential in forthcoming biomedical applications.
