Room Temperature Synthesis and Characterization of Hybrid Nanoparticles of NiMo over the Surface of Mixed Oxides (Al2O3-TiO2 and Al2O3-ZrO2) Using Ultrasound Radiation

摘要

Two novel catalysts of nano-hybridized Ni-Mo over Al2O3/TiO2 and Al2O3/ZrO2 were synthesized through a newly designed procedure by using ultrasonic irradiation and characterized by X-ray diffraction, UV-Vis diffuse reflectance spectra, FT-IR, energy dispersive X-ray spectroscopy and transmission electron microscopy. Then, the catalytic activities of these catalysts were examined in the oxidation of toluene by O-2 in various conditions of pressure, time and temperature. The products were analyzed by GC and GC-MS.
