Abstract

In this paper, tin 5,10,15,20-tetra-p-phenyl porphyrin (Cl₂Sn-TPP) encapsulated in a natural zeolite (clinoptilolite) and in synthetic zeolites (X-71, HZSM-5) were synthesized (by direct adsorption into the matrix cavities) and characterized by TGA/DSC, UV-Vis and FTIR techniques; subsequently, they have been tested as catalysts in the hydrogen peroxide decomposition reaction. UV-Vis and FTIR techniques put into evidence the highest adsorbtion rate of the metalloporphyrin on clinoptilolite. The thermal analysis of these materials explained their thermal behaviour, as a useful criterion for their application as catalysts in reactions that involve high temperatures, showing that the porphyrin – zeolite materials are resistant to high temperatures. Regarding the use of these materials in the decomposition of hydrogen peroxide, the best activity was encountered in the case of SnCl₂ – TPP/clinoptilolite when compared with the free zeolites.
