Abstract
甲烷氧化偶联CAf_2/SM_2O_3催化剂的研究周水琴,龙瑞强,黄亚萍,万惠霖,蔡启瑞(厦门大学化学系,固体表面物理化学国家重点实验室,厦门,361005)关键词甲烷氧化偶联,氟化钙,三氧化二钐,离子交换,氧物种甲烷氧化偶联制乙烯是催化领域中最活跃的?..
 
The results showed that,with the addition of CaF2 to Sm2O3,the catalytic properties For OCM were apparently improved.XRD analysis of the Fresh catalysts revealed the existence of Smof in 20%-80%CaF2/Sm2O3.XPS and IR spectra of O2-pre adsorbed CaF2/Sm2O3 samples taken at room temperature indicated the presence of O and Ospecies.O species could also be detected over 20%CaF2/Sm2O3 at 500℃ in situ IR spectroscopy,but it vanished over the Sm2O3 at the same temperature.
