| 摘要: |
Pd-Au bimetallic nanoparticles supported by silicon carbide have been prepared by plasma sputtering deposition, and employed as the catalyst for methane combustion. It is found that the bimetallic nanoparticles consist of tight-coupled Pd and Au particles, which are neither Pd-Au alloyed nor core-shell structured. The catalytic activity increases with the Pd loading in the catalysts. When the temperature is higher than 520 oC, Pd catalysts have an obvious drop in the catalytic activity due to the decomposition of PdO. However the introduction of Au can delay and weaken the drop. It indicates that there exists a synergistic combination between Pd and Au ？ oxygen transfers from Pd to Au at the temperature lower than 520 oC and from Au to Pd at higher temperature. |
