摘要：

The results from a study of the immobilization of cobalt(II) tetracarboxyphthalocyanine on a kaolinite functionalized with tris(hydroxymethyl)aminomethane are presented. The resulting materials were characterized by X-ray diffraction, thermal analyses, infrared and ultraviolet-visible absorption spectroscopy, and scanning and transmission electron microscopy. The detection of some bands typical of cobalt(II) tetracarboxyphthalocyanine by infrared spectroscopy confirmed immobilization of the complex on the amino-functionalized kaolinite and showed that there were no alterations in the interlayer hydroxyl groups of kaolinite, and also evidenced that immobilization occurred via the amine. The X-ray diffraction analysis revealed that the immobilization process prompted a structural change in the functionalized kaolinite, leading to the formation of a non-layered material. Solid state UV-Vis spectroscopy attested to the immobilization of the cobalt(II) tetracarboxyphthalocyanine on the amino-functionalized kaolinite, as verified from the appearance/displacement of some bands characteristic of the metal complex.
