| 英文摘要 | a series of nacl/b2o3/fe2o3 catalysts having a b/fe atomic ratio from 0 to 0.3 and 0.25 of na/fe atomic ratio were prepared for the oxidative coupling of methane (ocm). it was noted that nacl and b2o3 show a synergetic effect: nacl/fe2o3 produces mainly co2, but b2o3/fe2o3 and b2o3/nacl have poor activity. nacl/b2o3/fe2o3 catalyst has however high activity and selectivity. when the addition of b2o3 approaches 15 (at)%, the c-2 yield and selectivity reach their maxima, 17% and 75% respectively. the c2h4/c-2 ratio is as high as 76%. xrd, xps, h-2-tpr, o-2-tpd and in - situ mossbauer were employed to investigate the properties of the catalysts. results show there is a synergetic effect between nacl and b2o3 and feox surface. b2o3 modifies the redox ability of fe2o3. the nacl modified b2o3/feox has high reduction and lattice oxygen evaporation rates at 750 degrees c. the high activity and selectivity of the nacl/b2o3/feox catalyst are closely related with this synergetic effect. |
