“…[VO(acac) 2 ] was thus immobilized onto CMK-3 [346] and GO [374] through a Schiff condensation between the aminosilane and the carbonyl group of the acac ligand (Table 17, (Table 17, entries 3-4) [376].…”

“…[23,24] Hybrid organic-inorganic materials such as zirconium poly(styrene phenylvinylphosphonate)phosphate [25] have also been used for this purpose. Activated carbon, [26] multiwall carbon nanotubes, [21,27] nanostructured ordered carbon material, [21,28] porous silica, [29,30] MCM-41, [31,32] SBA-15, [21,33,34] zeolites [1,21,35,36] and magnetic nanoparticles [37] have also been used as insoluble supports. Inorganic supports generally have higher chemical stability and higher surface area than the organic ones.…”

Boehmite nanoparticles, with high surface area and high degree of surface hydroxyl groups, were prepared via hydrothermal-assisted sol-gel processing of aluminium 2-butoxide. The produced powder was covalently functionalized with 3-(trimethoxysilyl)propylamine, and then, in order to support vanadium oxosulfate and molybdenum hexacarbonyl complexes, all the terminal amine groups were changed to Schiff bases by refluxing with salicylaldehyde. These catalysts were applied in the epoxidation of cis-cyclooctene and other olefins with tert-BuOOH in CCl 4 . The catalytic procedures for both catalysts were optimized for various parameters such as solvent and oxidant. Recycling experiments revealed that these heterogeneous nano-catalysts could be repeatedly applied for the epoxidation of alkenes.

“…The band around 960 cm -1 is attributed to the Si-OH, whose intensity is decreased in V/NH 2 -SBA-15, possibly because of the anchoring of APTES and VO(acac) 2 on the support. A band at 1419 cm -1 is observed in the FT-IR spectrum of V/NH 2 -SBA-15, which can be attributed to the C-O bending vibration of VO(acac) 2 [34]. The V=O group is not observed at 997 cm -1 due to the Si-O-Si vibration.…”

“…NH 2 -SBA-15 shows very slow but continuous weight loss in the range of 150-1000°C due to the removal of the grafted APTES [30]. V/NH 2 -SBA-15 exhibits a sharp weight loss in 150-440°C followed by a slow weight loss, and the sharp decrease in weight can be interpreted as the decomposition of VO(acac) 2 [34]. The results further confirm the successful grafting of APTES and vanadium species in SBA-15.…”

An efficient catalyst for the direct hydroxylation of benzene to phenol with oxygen as the oxidant was developed by immobilizing the homogeneous vanadyl(IV) acetylacetonate (VO(acac) 2 ) on SBA-15 in which the support surface was functionalized by (3-aminopropyl)triethoxysilane. The as-prepared catalyst was characterized by various techniques including field-emission scanning electron microscopy, X-ray diffraction, nitrogen adsorption and desorption, Fourier transform infrared spectroscopy and X-ray photoelectron spectroscopy. The results show that the homogeneous vanadium species can be successfully immobilized on the amine functionalized SBA-15 and exhibits better catalytic performance in the hydroxylation of benzene with oxygen compared to other catalysts reported in the literature. The phenol yield significantly depends on the reaction conditions. Under the optimized reaction conditions, the phenol yield can reach 13.3 %, and the asfabricated V/NH 2 -SBA-15 shows better stability against leaching owning to strong interaction between vanadium atoms and amine group as compared to the V/SBA-15 sample.
