摘　　要： 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 had been synthesized and characterized by IR and TG/DTA.Its crystal structure had been determined by single crystal X-ray diffraction method.It crystallizes in a space group P-1 monoclinic crystal system.The N—H … N and N—H … O hydrogen-bonding are responsible for the supramolecular assembly and stabilization of the crystal structure.The（C5H7N2）3 AsMo12O40 ·5H2O/TiO2 catalysts were prepared by doping of TiO2.The photocatalytic eliminations of methanol and acetone steams were used as model reaction to evaluate the photocatalytic activity of the（C5H7N2）3 AsMo12O40 ·5H2O and the（C5H7N2）3 AsMo12O40 · 5H2O/TiO2 catalysts under ultraviolet light irradiation.The results showed that the order of catalytic activity is（C5H7N2）3 AsMo12O40 ·5H2O/TiO2（C5H7N2）3AsMo12O40 ·5H2O TiO2.Organic molecules C5H7N2 has strong affinity to organic matter,catalyst＇s adsorption for organic pollutants boost up,in favor of photocatalytic reaction.
