抄録

The oxidative dehydrogenation of ethane (ODE) reaction has been investigated over Sm<SUB>2</SUB>O<SUB>3</SUB>-LaF<SUB>3</SUB> and BaF<SUB>2</SUB> promoted Sm<SUB>2</SUB>O<SUB>3</SUB>-LaF<SUB>3</SUB> catalysts. Over Sm<SUB>2</SUB>O<SUB>3</SUB>-LaF<SUB>3</SUB>(molar ratio=1:1) and 16.7 mol% BaF<SUB>2</SUB>/Sm<SUB>2</SUB>O<SUB>3</SUB>-LaF<SUB>3</SUB>(molar ratio=1:1) high C<SUB>2</SUB>H<SUB>4</SUB> selectivities of 89.7% and 83.9% were achieved respectively. XRD and XPS characterizations show the electron donating ability of the catalysts are stronger that corresponding rare earth oxide and fluoride. The addition of BaF<SUB>2</SUB> can increase the number of the structure defects that may enhance the electron donating ability and increase the surface adsorbed oxygen concentration, thus should be favorable to improving the catalytic performance. However, the higher concentration of surface adsorbed oxygen is unfavorable for the ethene formation.
