Oxide-Supported Titanium Catalysts: Structure-Activity Relationship in Heterogeneous Catalysis, with the Choice of Support as a Key Step

The reactions of tetrakis(neopentyl)titanium, TiNp4 (1), with the surface of three solid oxides, silica, silica-alumina, and alumina, all partially dehydroxylated at 500 °C under vacuum were achieved. The resulting supported organometallic species react with dihydrogen to form the corresponding supported hydrides. The preparation of supported titanium hydrides on alumina is described here in detail, and the species obtained were extensively characterized by FTIR, solid-state NMR and EPR spectroscopy, and mass-balance analysis. The supported titanium hydride species were tested in three important reactions for petrochemistry: epoxidation of 1-octene, depolymerization of Fischer-Tropsch waxes, and polymerization of ethylene. The activities of titanium hydrides supported on alumina were compared to those of their silica- and silica-alumina-supported analogues.

Polyoxometalate-catalysed epoxidation of 1-octene with hydrogen peroxide in microemulsions coupled with ultrafiltration

Epoxidation of 1-octene with hydrogen peroxide catalysed by amphiphilic salts of peroxo tungstophosphate {PO4[WO(O2)2]4}3- in water-in-oil microemulsions is an efficient and environmentally benign reaction which, coupled with ultrafiltration, shows the potential for continuous production of epoxides.

Effect of Tetrahedral Ti in Titania-Silica Mixed Oxides on Epoxidation Activity and Lewis Acidity

The states of Ti in titania-silica mixed oxides have been studied by varying the Ti content.EXAFS analyses indicated that the amount of tetrahedral Ti species increased with a decrease in the Ti content reaching a maximum at 10 to 20 molpercent of Ti while octahedrally coordinated Ti predominated in the high Ti content region (Ti >/= 50 molpercent).Tetrahedral Ti species catalyse the epoxidation of oct-1-ene and cyclohexene using tert-butyl hydroperoxide as an oxidant.Lewis acid sites of the titania-silica also originated from the tetrahedral Ti species.Both epoxidation activity and Lewis acidity of the titania-silica were well explained by the coordinative unsaturation of the tetrahedral Ti site.

Dioxo-molybdenum(VI) unsymmetrical Schiff base complex supported on CoFe2O4@SiO2 nanoparticles as a new magnetically recoverable nanocatalyst for selective epoxidation of alkenes

In the present work, a dioxo-molybdenum unsymmetrical Schiff base complex, [MoO2(salenac-OH)], in which salenac-OH = [9-(2',4'-dihydroxyphenyl)-5,8-diaza-4-methylnona-2,4,8-trienato](-2), has been prepared and covalently immobilized on the sili

Catalytic oxygen atom transfer promoted by tethered Mo(VI) dioxido complexes onto silica-coated magnetic nanoparticles

The preparation of three novel active and stable magnetic nanocatalysts for the selective liquid-phase oxidation of several olefins, has been reported. The heterogeneous systems are based on the coordination of cis-MoO2 moiety onto three different SCMNP@Si-(L1-L3) magnetically active supports, functionalized with silylated acylpyrazolonate ligands L1, L2 and L3. Nanocatalysts thoroughly characterized by ATR-IR spectroscopy, TGA and ICP-MS analyses, showed excellent catalytic performances in the oxidation of conjugated or unconjugated olefins either in organic or in aqueous solvents. The good magnetic properties of these catalytic systems allow their easy recyclability, from the reaction mixture, and reuse over five runs without significant decrease in the activity, either in organic or water solvent, demonstrating their versatility and robustness.
