SBA-15 nanoporous silica was prepared by cooperation assembly of tetraethylorthosilicate  precursor in the presence of poly (ethylene glycol)–block- poly (propylene glycol)–block- poly (ethylene glycol) copolymer surfactant and functionalized with (3-aminopropyl) triethoxysilane (APTES) via sol-gel reaction to obtain APTES-SBA-15. Tetra-(p-chlorophenyl) porphyrin (TClPP) was synthesized using modified Alder- Longo method. Zinc was inserted into the TClPP using zinc acetate as a metal source The existance of zinc in porphyrin was confirmed by the appearance of Soret band and Q band in UV- vis spectra. ZnTClPP was also characterized using FTIR and NMR spectroscopy SBA-15 was modified with APTES to immobilize the metalloporphyrin on SBA-15 surface. The product (NH-SBA-15 ZnP) can be used as a heterogenous catalyst in various reactions. The formation of this material was confirmed by FTIR spectroscopy, XRD and BET adsorption.
