钼掺杂LaVO4上丙烷氧化脱氢
摘要:
研究了钼掺杂LaVO4催化剂的丙烷氧化脱氢催化性能.加入钼对丙烷氧化脱氢反应有很好的助催化作用.当丙烷转化率恒定在10％和20％时，丙烯选择性在LaMo0.1V0.9O4.05上分别达到了56％和43％，而在LaVO4上仅为36％和22％，这归结为钼掺杂催化剂上有利于丙烯生成的可活动氧物种的增加和催化剂氧化还原性的改变.

Propane Oxidative Dehydrogenation on Molybdenum Doped LaVO4 Catalyst
Abstract:
The catalytic behavior of molybdenum doped lanthanum vanadate for propane oxidative dehydrogenation was investigated.It was found that the addition of molybdenum showed a positive promoting effect to propane oxidative dehydrogenation.56％ and 43％ of C3H6 selectivities were obtained over LaMo0.1V0.9O4.05 at 10％ and 20％ C3H8 conversion respectively ,while the selectivities on LaVO4 were only 36％ and 22％ at the isoconversion,which can be attributed to an increase of the mobile oxygen species beneficial to propene formation and to the change of the redox properties of the molybdenum doped catalysts.
