项目摘要
The structure of the SrBi_3O_4Cl_3 catalyst was analyzed by a Rietveld analysis. In the X1X2 structure, metal-oxygen sheets were separated by single chlorine layers and double chlorine layers alternately. SrBi_3O_4Cl_3 crystallized in space group 14/mmm with lattice parameters of a=3.9370(1), c=27.0177(7)Å. The structure showed that between two Bi(1) and Bi(2) sites, the former being of Bi in the metal-oxygen sheet faced the single chlorine sheet and the later faced the double chlorine sheet, strontium ions occupied the Bi(2) site only, and did not occupy the Bi(1) site. Based on this structural materials, much highly selective and active catalysts were developed. 74% yield of ethene has been attained in the oxidative dehydrogenation of ethane at 640℃ over the catalyst having a composition of KSr_2Bi_3O_4Cl_6.The lanthanum-substituted complex metal chloride oxide catalysts were also investigated. With the replacement of lanthanum ion in the cation-oxygen sheet of SrBi_3O_4Cl_3 catalyst … More s, the SrBi_<3-n>La_nO_4Cl_3 (n【less than or equal】0.75) catalyst remained the X1X2 structure, the activity for the oxidative dehydrogenation of ethane were promoted prominently. The Rietveld analysis of the XRD patterns of SrBi_<2.25>La_<0.75>O_4Cl_3 catalyst revealed that the increased coordination number of the metal ion facing the double chlorine sheet from 8 to 9 resulted in a decrease of the thickness of the double chlorine sheet. The interaction between the metal-oxide sheet and the chlorine sheet became stronger, which is supported by a reduced binding energy of chlorine in SrBi_<2.25>La_<0.75>O_4Cl_3. It is suggested that the activation of structural chlorine into a radical form is promoted by the replacement with lanthanum ion, which turns out to be the increase of the oxidation activity of ethane.The structure of the Bi_2SmO_4Cl catalyst was refined by Rietveld method. The space group is P4/mmm, a=3.8938(1)Å, c=8.9691(3)Å. It can be seen that the [Bi_2SmO_4] layer is present, which may be regarded as a'triple' rather than'double' fluorite unit. This cationic layer is balanced by the simplest possible anionic layer, Cl^-, hence the structure has the layer sequence -Cl-[Bi_2SmO_4]- Cl- etc. along the crystallographic c axis. La ion is coordinated only by oxide layers and Bi by both oxide and chloride layers. The Bi_2LaO_4Cl catalysts showed a high activity for the oxidation of ethane, but the selectivity to ethene were low, which can be attributed to the promoted oxidation ability of La-oxygen-La sheets.

采用Rietveld分析法对SrBi_3O_4Cl_3催化剂的结构进行了分析。在X1X2结构中,金属-氧片被单氯层和双氯层交替分隔。 SrBi_3O_4Cl_3结晶于14/mmm空间群,晶格参数为a=3.9370(1),c=27.0177(7)Å。结构表明,在两个Bi(1)和Bi(2)位之间,金属氧片中的Bi前者面向单氯片,后者面向双氯片,锶离子仅占据Bi(2)位,不占据Bi(1)位。基于这种结构材料,开发了许多高选择性和高活性的催化剂。在KSr_2Bi_3O_4Cl_6组成的催化剂上,乙烷在640℃下氧化脱氢,乙烯收率达到74%。还对镧取代的复合金属氯化物催化剂进行了研究。随着SrBi_3O_4Cl_3催化剂阳离子氧片中镧离子的取代,SrBi_<3-n>La_nO_4Cl_3(n【小于等于】0.75)催化剂仍保持X1X2结构,乙烷氧化脱氢活性显着提高。 Rietveld对SrBi_<2.25>La_<0.75>O_4Cl_3催化剂的XRD图谱分析表明,面向双氯片的金属离子配位数从8增加到9,导致双氯片厚度减小。金属氧化物片和氯片之间的相互作用变得更强,这是由SrBi_<2.25>La_<0.75>O_4Cl_3中氯的结合能降低所支持的。表明镧离子的取代促进了结构氯活化成自由基形式,从而提高了乙烷的氧化活性。采用Rietveld法对Bi_2SmO_4Cl催化剂的结构进行了精修。空间群为P4/mmm,a=3.8938(1)Å,c=8.9691(3)Å。可以看出存在[Bi_2SmO_4]层,可以将其视为“三重”而不是“双重”萤石单元。该阳离子层由最简单的阴离子层 Cl^- 平衡,因此该结构沿晶体 c 轴具有层序列 -Cl-[Bi_2SmO_4]- Cl- 等。 La 离子仅通过氧化物层配位,而 Bi 则通过氧化物层和氯化物层配位。 Bi_2LaO_4Cl催化剂对乙烷的氧化表现出较高的活性,但对乙烯的选择性较低,这可能归因于La-氧-La片层的促进氧化能力。较少的
