The TPD of surface oxygen of Fe_2O_3, Sb_2O_4 and other five mixedoxides with atom ratio Sb/Fe from 1/9 to 9/1 have been investigated. A smallamount of oxygen is desorbed from Fe_2O_3 at 200-450℃ while for Sb_2O_4the desorption peak of oxygen appears after 700℃ and in the case of mixedoxides both α and β oxygen are found to be during TPD after 400℃. It isfound that the activation energy of desorption of a oxygen increases withthe increase of Sb content and that α oxygen is more reactive than β oxygenfor the...

The TPD of surface oxygen of Fe_2O_3, Sb_2O_4 and other five mixedoxides with atom ratio Sb/Fe from 1/9 to 9/1 have been investigated. A smallamount of oxygen is desorbed from Fe_2O_3 at 200-450℃ while for Sb_2O_4the desorption peak of oxygen appears after 700℃ and in the case of mixedoxides both α and β oxygen are found to be during TPD after 400℃. It isfound that the activation energy of desorption of a oxygen increases withthe increase of Sb content and that α oxygen is more reactive than β oxygenfor the oxidation of propylene. It is shown also that NH_3 adsorption sitesare of different strength depending on the content of α and β oxygen in Fe-Sb oxide. It is concluded that suitable bonding strength of surface oxygenin Fe-Sb oxides should be the main cause of high activity and selectivity inthe ammoxidation of propylene.

研究了Fe_2O_3和Sb_2O_4及Sb/Fe比由1/9至9/1五种复合氧化物表面氧的TPD行为。Fe_2O_3在200~450℃间有少量氧脱出,Sb_2O_4在700℃以后出现脱氧峰,而Sb/Fe复合氧化物则出现所谓α和β脱氧峰。随Sb/Fe比增加α氧的脱附活化能也增高,Sb/Fe比为3/7、5/5和7/3时分别为33、36、51kcal/mol。Fe-Sb氧化物中α氧比β氧对烯烃氧化具有更高的活性。在50—275℃范围内NH_3在Fe-Sb氧化物上的吸附等温线符合Freundlich式,同时由NH_3的TPD可明显看出Fe-Sb氧化物具有不同强度的吸附中心,它们与所含表面氧有关,但表面氧对NH_3的氧化是很弱的。讨论了烯烃选择氧化反应与表面氧强度之间的联系。

The more the specific enrichment in antimony, the better the selectivity for benzaldehyde. The sample which contains...

Samples of mixed oxides of Sb/Fe with different ratios calcined at 500℃ have been investigated by X-ray diffraction, Moessbauer spectroscopy, magnetic susceptibility, infrared spectroscopy, and surface micro-area element analysis. The catalytic activity of the oxidation of toluene to benzaldehyde has also been studied. The results showed that antimony was enriched on the surface of the catalysts. The more the specific enrichment in antimony, the better the selectivity for benzaldehyde. The sample which contains Sb_2O_4 only had the highest selectivity for benzaldehyde. When Sb/Fe=5, Sb_2O_4 and FeSbO_4 occurred in the sample, and an FeSb_2O_6 phase also existed. While the amount of iron was increased in the samples, i. e., when Sb/Fe ratio was higher than 5, the phases of the samples were Sb_2O_4 and FeSbO_4. Solid solubilization was observed with the samples prepared under the conditions adopted. In addition, the mechanism of the toluene oxidation reaction on Fe-Sb oxide catalysts was discussed in detal.

对不同Sb/Fe比,500℃焙烧的样品,采用了X射线衍射、穆斯堡尔谱、比磁化强度、红外光谱、表面微区元素分析及甲苯氧化生成苯甲醛的活性测定等进行了研究。结果表明,在催化剂的表面上均有锑富集,锑的比富集量愈大,苯甲醛的选择性也愈高。不含铁样品的物相为Sb_2O_4,生成苯甲醛的选择性最高。当Sb/Fe=5时,物相中除Sb_2O_4、FeSbo_4外,还有FeSb_2O_6生成。随着Fe含量增加,Sb/Fe比高于5时,样品物相为Sb_2O_4和FeSbO_4。在所采用的制备条件下得到的Fe-Sb样品中,观察到有明显的固溶作用。此外,本文还对Fe-Sb氧化物催化剂上甲苯的反应机理进行了讨论。
