Iron-containing MCM-41 catalysts for Baeyer–Villiger oxidation of ketones using molecular oxygen and benzaldehyde

Aerobic Baeyer–Villiger oxidation of cyclic ketones over periodic mesoporous silica Cu/Fe/Ni/Co-HMS-X

“…In the following experiments, we chose DCE as the organic medium to perform the oxidation reaction as reported in literature. [28] The Baeyer-Villiger oxidation reactions were carried out at different temperatures to investigate the influence of reaction temperature on the, cyclohexanone conversion and product distribution. The effect of the reaction temperature is summarized in Tables 2.…”

Dehydrogenation of Cyclohexanol on Fe, Ti-MCM-41 Mesoporous Materials

“…Mössbauer spectroscopy is applied for more detailed characterization of the iron species [5,[40][41][42]. The spectra of all studied materials after different pretreatments are presented in Fig.…”

“…MCM-41 silica materials, with their uniform mesoporous channel structure and high specific surface area are of particular interest as catalyst support [1][2][3][4][5][6][7][8]. A wide variety of metal ions (Fe, Ti, V, Cr, Cu, etc.)…”

Synthesis, characterization, and photocatalytic activity of MCM-41 and MCM-48 impregnated with CeO2 nanoparticles

“…These materials containing various transition metals are used as heterogeneous catalysts for many organic compound reactions [2,3]. Pure silica mesoporous material has only a few crystal defects and low reaction activity.…”

“…Because of these disadvantages, researchers attempt to introduce some nanoparticles into this mesoporous material. The successful usages of the transition and rare earth metals in the catalysts are mainly the promoters; in oxides or in the microporous material, some attention have been paid to the combination of the transition and rare earth metals with the mesoporous materials in which the transition and rare earth metals are used as the active components of catalyst [2][3][4].…”
