负载化金属卟啉化合物催化剂结构的表征──Ⅰ红外光谱和紫外漫反射光谱

STUDY ON THE STRUCTURE OF SUPPORTED METALLOPORPHYRINS──ⅠInfrared Spectrum and Diffuse Reflectance Electronic Spectrum

用红外、紫外及其漫反射光谱对催化剂的结构进行了测定。载体（氯球、ｒ—Ａｌ２Ｏ３、ＴｉＯ２）使金属叶咐吸收峰红移１０～３０ｎｍ，与推电子基的效应相一致。漫反射光谱证实聚合物负载的铁卟啉、锰卟啉、铬卟啉生成了氧络金属卟啉．而负载化铜卟啉、钻卟啉来生成相应的氧络金属卟啉。红外光谱进一步证实了金属卟啉与载体间的相互作用。

The structures of the metalloporphyrin catalysts have been investigated by infrared spectrum(IR)and diffuse reflectance electronic spectrum (DRES).The supporters increased the wavelengths of the absorption-peaks of metalloporphyrins by 10 ～ 30nm.DRES showed that a new spedes O……metalloporphyrin was generated in Fe-Por.Mn Por.Cr-Por.Supported by polymer.But it was not discovered in Cu-per. and Co-per.supported by polymer.The Interaction of the supporter with metalloporphyrin has also been confirmed by IR.
