| 中文摘要: |
| 合成了一种用作前驱体的，具有八面体结构新型水溶性的金属复合离子型化合物碳酸二羟基.四氨合铂(IV)二水合物([Pt(NH3)4(OH)2]CO3.2H2O)，用元素分析和X射线单晶衍射仪(XRD)对其结构进行了表征，用热重-差热(TG-TDA)测试其热分解特性，并对比评价制备DOC催化剂的性能。结果表明，化合物为单斜晶系、P21/c空间群，晶胞参数为:a=0.88191(14) nm，b=1.17817(18) nm，c=1.01533(16) nm，V=0.9978(3) nm3，Z=4，R1=0.0403，wR2=0.1235，R1=0.0466，wR2=0.1353。其晶体结构为以Pt(IV)为中心与4个NH3和2个羟基配位形成八面体的二价阳离子；TG-DTA测试显示化合物分解峰出现在223.8℃；制备得到的DOC催化剂催化活性和起燃温度优于传统前驱体化合物。 |
| 英文摘要: |
| A new water-soluble, ion-type platinum(IV) complex, [Pt(NH3)4(OH)2]CO3.2H2O, was synthesized and characterized by the element analysis and single crystal X-ray diffraction. Its thermal decomposition characteristics were characterized by TG-TDA. Its cystal belongs to monoclinic space group P21/c, and its unit cell parameters are: a=0.88191(14) nm, b=1.17817(18) nm, c=1.01533(16) nm and V=0.9978(3) nm3; Z=4, R1=0.0403, wR2=0.1235, R1=0.0466, wR2=0.1353. The crystal data shows that Pt(IV) acted as the center ion coordinates with four NH3 in a square planar and two hydroxyl groups in opposite axial position, forming a octahedral bivalent cation. TG-TDA results showed that the peak decomposition temperature was 223.8℃. The prepared diesel oxidation catalysts using the compound have better catalytic activity and light-off temperature than conventional precursors. |
