| مستخلص: |
Pd/Al2O3catalysts modified by different amount of magnesium were fabricated for catalytic combustion of methane (CCM). After the introduction of different amount of magnesium, Al2O3, MgAl2O4-like mixed oxide and Mg(Al)Oxsolid solution were formed. Owing to the formation of distinguished supports, the supported Pd species, i.e. metallic Pd, PdOxand support-Pd oxide complex were formed, and they were quite different in relative content and Pd↔PdO transformation ability. It was found that PdOxwas active at low temperature, while metallic Pd particles and support-Pd oxide complex were active at high reaction temperature. The one with Mg/Al mole ratio of 1:3 was the most easily in Pd↔PdO transformation, demonstrating the best catalytic activity towards CCM reaction. |
