TUD-C-supported tungsten oxide-doped titania catalysts for cyclohexane oxidation
A new oxidation catalyst of Technische Universiteit Delft-Crystalline (TUD-C)-supported tungsten oxide-doped titania (WO3-TiO2/TUD-C) has been successfully synthesized. WO3-modified TiO2 was reported as a potential oxidation catalyst. However, the low surface area and porosity have restricted the ca...

A new oxidation catalyst of Technische Universiteit Delft-Crystalline (TUD-C)-supported tungsten oxide-doped titania (WO3-TiO2/TUD-C) has been successfully synthesized. WO3-modified TiO2 was reported as a potential oxidation catalyst. However, the low surface area and porosity have restricted the catalytic performance of this material. In order to overcome this problem, a mesoprorous zeolitic compound of TUD-C was used as a catalyst support for WO3-TiO2 in this work.
