“…11 Magnetic particles can also act as seeds for MOF crystallization; 16 the resulting magnetically active composite (Magnetic Framework Composites, MFCs) 17 can be used for dynamic localization, 18 triggered heating, 19 and catalysis. 20,21 As both enzymes and magnetic particles were separately used to spontaneously induce the ZIF-8 formation in aqueous conditions, 22 we hypothesized that the simultaneous use of both could lead to the one-step synthesis of magnetically and catalytically active ZIF composites. This would result in a new straightforward procedure for the preparation of recyclable MOF-based biocatalysts.…”

“…Furthermore, the use of ceramics as precursors allows reflections to be carried out under mild conditions . In this study, Fe 3 O 4 MNPs have been encapsulated into the Cu‐based ceramic material used as a precursor for the preparation of magnetic HKUST‐1 composites . The Fe 3 O 4 @Cu 2 (OH) 3 NO 3 composite was subsequently converted to Fe 3 O 4 @HKUST‐1 through immersing to an ethanol solution containing H 3 BTC (Figure ).…”

Metal-organic frameworks (MOFs)o ffer ample characteristics, such as easy synthesis, high surface area, tunable porosities, open metal sites, post-synthesis modification, making them attractive for diverse applications. Since magnetic particles can be positioned and separated by a magnetic field, magnetic framework composites (MFCs)h ave attracted tremendous attention.I nt his review,d ifferent methods of preparingM FCs, including direct mixing, in-situ growth of magnetic particles, embedding method, layer-bylayer growth method and encapsulationm ethod, will be discussed in detail. Moreover,t heir applications in catalysis, adsorption, biomedicine and sensing will also be introduced.

“…[21] have reported one-pot synthesis of 1,4-DHP in EtOH with an excellent (95%) yield in the presence of HKUST-1. Toyao et al [22] describe examples of catalysts which consist of nanoparticles loaded onto HKUST-1. Fe 3 O 4 @HKUST-1 and Pd/Fe 3 O 4 @HKUST-1 have been used for one-pot deacetalisation and Knoevenagel condensation reactions as well as in the hydrogenation of olefins.…”

HKUST-1-Supported Cerium Catalysts for CO Oxidation

The synthesis method of metal–organic frameworks (MOFs) has an important impact on their properties, including their performance in catalytic reactions. In this work we report on how the performance of [Cu3(TMA)2(H2O)3]n (HKUST-1) and Ce@HKUST-1 in the reaction of CO oxidation depends on the synthesis method of HKUST-1 and the way the cerium active phase is introduced to it. The HKUST-1 is synthesised in two ways: via the conventional solvothermal method and in the presence of a cationic surfactant (hexadecyltrimethylammonium bromide (CTAB)). Obtained MOFs are used as supports for cerium oxide, which is deposited on their surfaces by applying wet and incipient wetness impregnation methods. To determine textural properties, structure, morphology, and thermal stability, the HKUST-1 supports and Ce@HKUST-1 catalysts are characterised using X-ray diffraction (XRD), N2 sorption, scanning electron microscopy (SEM), high-resolution transmission electron microscopy (HRTEM), X-ray photoelectron spectroscopy (XPS), Fourier transform infrared spectroscopy (FT-IR), and thermogravimetric analysis (TGA). It is proven that the synthesis method of HKUST-1 has a significant impact on its morphology, surface area, and thermal stability. The synthesis method also influences the dispersion and the morphology of the deposited cerium oxide. Last but not least, the synthesis method affects the catalytic activity of the obtained material.
