层状嵌接式卟啉钴的合成、表征及其对H_2O_2催化降解研究

Synthesis and Characterization of Layered Phosphotoantimonic Acid-Intercalated Cobalt Porphyrin and Its Catalytic Behaviour to Hydroperoxide Decomposition

采用有机溶剂在层状锑磷酸中在位分步合成了层状嵌接式卟啉钴材料；用红外光谱、紫外可见光谱、X射线衍射和顺磁共振技术对其进行了表征．该合成材料对H2O2降解反应体系的进一步研究表明，卟啉钴嵌接于锑磷酸层状环境中对H2O2具有良好的催化降解活性和抗失活稳定性．

A stepwise synthesis method was used to intercalate cobalt tetraphenylporphyrin into the layered phosphotoantimonic acid host material. The characterization of the purified sample layered phosphotoantimonic acid-intercalated cobalt porphyrin was made by the method of IR, powder XRD, UV-Vis and EPR. Layered phosphotoantimonic acid-intercalated cobalt porphyrin exhibits a fairly catalytic behaviour to hydroperoxide decotnposition, which indicates the intercalation of the porphyrin could result in the prevention of the formaaion of u-dimers and the increased catalytic capabilities.
