| Summary: | 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. The TUD-C-supported 1 mol% WO3-TiO2 was synthesized by adding pre-synthesized WO3-TiO2 onto the TUD-C support. Both X-ray diffractometry and Fourier transform infrared analyses indicated MFI zeolitic framework formation in the TUD-C-supported 1 mol% WO3-TiO2. Both surface area and porosity of the resulting WO3-TiO2/TUD-C were significantly higher than those of bare WO3-TiO2. The catalytic performance of the resulting materials was evaluated through cyclohexane oxidation at 70oC for 4 hours. It has been demonstrated that the catalytic activity of WO3-TiO2 increased approximately 2-fold after loading on TUD-C support. |
