合成了配合物(C5H7N2)3AsMo12040·5H2O,对其进行了IR和TG/DTA分析,并用X-射线单晶衍射仪测定了晶体结构。配合物晶体属于单斜晶系,P-1空间群。配合物经N—H…N和N—H…O氢键相连组成超分子化合物,氢键稳定了晶体结构。将该配合物掺杂TiO2制备复合催化剂(C5H7N2)3AsMo12040·5H2O/TiO2,以甲醇、丙酮气体消除反应为模式反应评价该配合物和复合催化剂的光催化性能。结果表明,复合催化剂的催化活性优于配合物本身和TiO2。配合物中的有机分子,对有机物有强的亲和性,更容易吸附有机分子利于光催化反应的进行。
The complex (C5H7N2) 3AsMo12040 · 5H2O was synthesized and characterized by IR and TG / DTA. The crystal structure was determined by X-ray single crystal diffraction. Complex crystals belong to monoclinic system, P-1 space group. The complexes are linked by N-H ... N and N-H ... O hydrogen bonds to form supramolecular compounds, and the hydrogen bonds stabilize the crystal structure. The composite was doped with TiO2 to prepare the composite catalyst (C5H7N2) 3AsMo12040 · 5H2O / TiO2. The photocatalytic performance of the complex and the composite catalyst was evaluated by using the elimination reaction of methanol and acetone as the mode reaction. The results show that the catalytic activity of the composite catalyst is better than that of the complex itself and TiO2. Complex organic molecules, the strong affinity for organic matter, easier adsorption of organic molecules conducive to the photocatalytic reaction.
