| 英文摘要 | Pd supported on TiO2-Al2O3 binary oxides prepared by coprecipitation method has been investigated for the total oxidation of methane. All Pd/TiO2-Al2O3 catalysts show higher activity than Pd/Al2O3 and Pd/TiO2. Among them, Pd/2Ti-3A1 with a Ti/Al ratio of 2 to 3 has a T-90% of 395 degrees C at a gas hourly mass velocity of 33000 mL/(h center dot g), which is at least 50 degrees C lower than that of Pd supported on single metal oxide Al2O3 or TiO2. The results of TPR and O-18-isotope exchange experiments demonstrated that the excellent activity of Pd/2Ti-3A1 was due to its high oxygen mobility and moderate reducibility, which is in accordance with our previous work. XPS results indicated that the dispersion of Pd was not the key factor to influence the catalytic activity. |
