Synthesis, characterization of Ga-TUD-1 catalyst and its activity towards styrene epoxidation reaction

Styrene epoxidation reaction has drawn attention from both academia and industry. After the synthesis of SBA-15 the research on mesoporous family has enriched by TUD-1 mesoporous material. Doped and undoped TUD-1, has been exploited for various oxidation reactions either as such or as a support for different active component. In this paper we report the characterization of recently developed Ga-TUD-1 catalyst with three different Ga/Si ratio (1/100, 2/100, 4/100) by BET SA, FTIR, UV–Vis, DRIFT, SEM, TEM, 29Si NMR techniques. A steady activity of the catalyst towards styrene epoxidation without any loss of efficiency up to 48 h of reaction was found.
