“…This result indicated that the quaternary ammonium group was successfully immobilized onto Cu(BDC-NH 2 )(DMF) through the quaternization reaction. Similar results have also been reported by Wang and co-workers [ 47 ]. Wang et al found that quaternization reaction of the MOFs could significantly decrease their surface areas.…”

In this study, quaternary-ammonium-functionalized metal–organic frameworks (MOFs) Et-N-Cu(BDC-NH2)(DMF), were prepared, characterized, and applied for the highly effective removal of metal cyanide complexes, including Pd(CN)42−, Co(CN)63−, and Fe(CN)63−. Batch studies were carried out, and the maximum adsorption capacities of Pd(II), Co(III), and Fe(III) reached 172.9, 101.0, and 102.6, respectively. Adsorption was rapid, and equilibrium was established within 30 min. Et-N-Cu(BDC-NH2)(DMF) exhibited high thermal and chemical stability. Furthermore, absorbed Pd(CN)42− was selectively recovered by two-step elution. First, Co(CN)63− and Fe(CN)63− were eluted with a 1.5 mol L−1 KCl solution. Elution rates of Co(CN)63− and Fe(CN)63− were greater than 98.0%, whereas the elution percentage of Pd(CN)42− was less than 2.0%. Second, >97.0% Pd(CN)42− on the loaded MOFs was eluted using a 2.0 mol L−1 KI solution. The recovery rate of Pd(CN)42− was greater than 91.0% after five testing cycles. Adsorption isotherms, kinetics models, and adsorption thermodynamics of Pd(CN)42− on Et-N-Cu(BDC-NH2) (DMF) were also systematically investigated. The Et-N-Cu(BDC-NH2) (DMF) absorbent exhibited a rapid, excellent ability for the adsorption of metal cyanide complexes.

“…Slight difference in the diffractogram was detected probably due to the variation of ligand, the flexible behavior in Cu(BDC)(DMF) structure, and the non-isotropy during sample preparation [ 44 ]. Similar quaternization reaction of the MOFs has also been reported by Wang and co-worker s [ 47 ].…”

“…Diffraction peaks of the supporting material ( Fig. 7a-black pattern) were observed at 2θ = 6.8, 9.8 and 13.8 which is in agreement with the structure of IRMOF-3 [34]. After palladium deposition the intensity of peaks has been slightly decreased but they were still present showing that the crystal structure of IRMOF-3 is preserved (Fig.…”

Pd Supported IRMOF-3: Heterogeneous, Efficient and Reusable Catalyst for Heck Reaction

IRMOF-3 with a high surface area prepared by a hydrothermal method was used for deposition of Pd(OAc) 2 on IRMOF-3 particles. The final catalyst was characterized with FT-IR, nitrogen physisorption, thermogravimetry, scanning electron microscopy, transmission electron microscopy combined with energy dispersive X-ray analysis, wide angle X-ray diffraction spectroscopy and X-ray photoelectron spectroscopy. The prepared porous catalyst was effectively used in the Heck coupling reaction in the presence of an organic base. The reaction parameters such as the type of base, amounts of catalyst and solvents, temperature were optimized. The catalyst was then easily separated, washed, and reused 4 times without significant losses of catalytic activity.

“…Although many homogeneous catalysts were found to be effective at low pressure and temperature [6,7], the difficult and costly separation of the catalysts from the reaction products represents a serious drawback to their application. Consequently, various heterogeneous catalysts, such as metal oxides [10,11], immobilized complexes or ionic liquids [12][13][14], titanosilicates [15], metal-organic frameworks [16][17][18][19], and zeolites [19], were tested. However, most of these heterogeneous systems require high pressures and high temperature.…”

Carbon nanotubes (CNTs) were functionalized and were then used as supports of Fe 1.5 PMo 12 O 40 (FePMo) Keggin heteropolyanions catalysts. The characterization of the resulting catalysts was investigated by inductively coupled plasma spectrometry (ICP), Fourier transform infrared (FTIR) spectra, X-ray diffraction (XRD), ultraviolet-visible (UV-Vis) light spectroscopy, and transmission electron microscopy (TEM). FTIR and XRD results confirmed that FePMo was bounded on CNTs successfully and the Keggin structure was preserved. Characterization by TEM showed that solids with high FePMo content exhibited aggregation of FePMo in large particles. The as-prepared catalysts were tested in the synthesis of propylene carbonate (PC) from CO 2 and propylene oxide (PO) in a solvent-free reaction and under mild conditions. Effects of various parameters, such as reaction temperature, reaction time, FePMo content on the support, and catalyst loading on the reaction, were investigated. It has been found that CNTs supported FePMo achieved 57.7% PO conversion and 99.0% PC selectivity, whereas unsupported FePMo led only to 8.5% conversion and 48.6% selectivity. The remarkable enhancement of the catalytic activity over the supported catalyst can be attributed mainly to the better dispersion and reactivity of the FePMo catalyst in the supported material.
