Artificial sunlight and ultraviolet light induced photo-epoxidation of propylene over V-Ti/MCM-41 photocatalyst
The light irradiation parameters, including the wavelength spectrum and intensity of light source, can significantly influence a photocatalytic reaction. This study examines the propylene photo-epoxidation over V-Ti/MCM-41 photocatalyst by using artificial sunlight (Xe lamp with/without an Air Mass 1.5 Global Filter at 1.6/18.5 mW·cm(-2)) and ultraviolet light (Mercury Arc lamp with different f...
متن کاملReal-Time Raman Monitoring during Photocatalytic Epoxidation of Cyclohexene over V-Ti/MCM-41 Catalysts
A series of Vand/or Ti-loading MCM-41 catalysts are successfully synthesized with a hydrothermal method. The photocatalytic and thermal epoxidations of cyclohexene in the presence of tert-butyl hydroperoxide (t-BuOOH) were investigated with real-time monitored by NIR-Raman spectroscopy. It suggests that both Vand Ti-loading can be responsible for the cyclohexene epoxidation. Moreover, the compl...
متن کاملNew Molybdenum Epoxidation Catalyst Derived From Nanoporous MCM-41 Supported Glycine Schiff-Base
Covalent grafting of the nanoporous molecular sieve MCM-41 with 3- aminopropyl trimethoxysilane and acetyl acetone (acac) successively gave modified MCM-41 (acacAmpMCM-41). Reaction of the resulted material with glycine afforded the corresponding supported glycine Schiff base ligand and subsequent reaction with [bis(acetylacetonato)dioxomolybdenum(VI)] was lead to molybdenum complex suppor...
متن کاملImmobilized Vanadium Compounds within Nanoreactors of Al-MCM-41 as Catalyst for Epoxidation of Alkenes
VO2+ and its complexes with ethylenediamine (en), acetylacetonate (acac), 2, 2’-bipyridine(bpy) ligands, immobilized within nanoreactors of Al-MCM-41 designated as VO2+/Al-MCM-41 or VOL2/Al-MCM-41, were prepared and characterized by X-ray powder diffraction (XRD), FT-IR, BET nitrogen adsorption-desorption and chemical analysis techniques. VO2+/Al-MCM-41 and VOL2/Al-MCM-41 were found to catalyze...
متن کاملImmobilization of Cu(II)-Histidine Complex on Al-MCM-41 as Catalyst for Epoxidation of Alkenes
Cu(II) complex with L-histidine (His) ligand, immobilized within Al-MCM-41, designated as Cu(His)2/Al-MCM-41 was prepared and characterized by powder X-ray diffraction (XRD), nitrogen adsorption desorption, FTIR, UV-Vis and chemical analysis techniques. The surface area and pore volume were found to decrease after immobilization of Cu(II) complex on Al-MCM-41. It was found that Cu(His)2/Al-MCM-...
