Activity of Ti-Beta Catalyst for the Selective Oxidation of Alkenes and Alkanes

Catalytic epoxidation of α-pinene with molecular oxygen using cobalt(II)-exchanged zeolite Y-based heterogeneous catalysts

“…Most of these studies describe the use of homogeneous catalysts and only few papers deal with the application of heterogeneous catalysts [8,9]. Molecular sieves containing metal center in their framework were reported for some epoxidation reactions recently [10][11][12][13][14].…”

Catalytic Oxidations Over Titanosilicate Zeolites

“…Corma et al [ 84 ] fi rstly reported the oxidation of various olefi ns and alkanes over Ti-Beta zeolite. For small molecules without steric restrictions to diffuse inside the pores of Ti-Beta and TS-1, the TS-1 catalyst is generally more active than Ti-Beta.…”

Mesoporous Titanium–Silica Composite Encapsulated γ-Fe2O3: Novel Magnetically Recyclable Heterogeneous Catalysts for Olefin Epoxidation Reactions

“…Titanium-containing mesoporous molecular sieves have been used as efficient heterogeneous catalysts in the epoxidation of alkenes [11,12]. Since the first synthesis of Ti-MCM-41 by Corma et al [13], various kinds of titanium-containing mesoporous molecular sieves, such as Ti-HMS [14][15][16], Ti-MCM-48 [17][18][19], Ti-MSU-1 [20] and Ti-SBA-15 [21,22] have been synthesized and employed as catalysts for epoxidation reactions. However, these conventional heterogeneous catalysts usually need tedious procedures such as filtration and centrifugation for recycling after reactions, which inevitably lead to the leaching of catalyst.…”
