| 英文摘要 | catalytic decomposition of n2o was studied over co substituted mg-y type hexaferrites (ba2mg2-xcoxfe12o22, x = 0.4-2.0). the materials were synthesized by a sal-gel method using citric acid as the chelator followed by calcination at 1223 k for 5 h. x-ray diffraction, thermogravimetric analysis/derivative thermogravimetric, scanning electron microscopy, and n-2 adsorption techniques were used to confirm the formation of hexaferrite. the ba2mg2-xcoxfe12o22 catalysts displayed good activity for decomposition of high concentration n2o (30 vol%), and complete substitution of mg for co lowered the complete conversion temperature from 1123 k to 973 k. increasing calcination temperature suppressed the catalytic activity by deteriorating surface area. moreover, coupling microwave discharge significantly boosted the catalytic activity. co substituted mg-y type hexaferrites are potentially active and thermally stable to be used as catalyst for high concentration n2o decomposition.
