Abstract
This project aims at developing a simple process for the preparation of heterogeneous catalysts consisting of the second-generation metalloporphyrins: 5,10,15,20 (mesotetrakis (4-hydroxyphenyl) porfirinaferro (III), FeTPP (OH) 4 in silica matrices containing particles of the spherical shape obtained by the sol-gel method Stober and spray pyrolysis technique for application as catalysts fo…
