In this project, first, zirconium phosphate (ZP) nanoparticles were prepared and then H + ions on the surface of the ZP nanoparticles were exchanged with Fe (III) cations by using impregnation method under reflux condition. This inhomogeneous catalyst was called ion exchanged ZP with Fe (III) (ZPFe) and chracterized by using ICP, XRD, SEM, TEM, and BET analyses. ICP analysis showed Fe, Zr, P and O elements according with applied amounts of these elements to synthesis of the catalyst. Identified phases in XRD ananlyses were consistent with original sample, completely. With ananlytical techniques SEM and TEM catalyst size in nanoscale was confirmed. BET analysis demostrated that pore size of Ce/Zr/Fe nanocatalyst was in the range of macroporous scale. Then, three different types of reactions were investigated by using this nanocatalyst, including protection of aromatic aldehydes by converting them to relevant acylals through acetic anhydride, acetylation of phenol and its derivatives by acetic anhydride, and oxidation of alchohols to corresponding carbonyl compounds by hydrogen peroxide. Obtained products from each type of aforementioned reactions, after extraction and purification, were characterized by using FT-IR and 1 HNMR spectroscopies and their structures were confirmed. Prepared catalyst was extracted simply at the end of each reaction by using centrifuge apparatus and recycled by using simple process. Reaction yields were high and yield losses were negligible after the catalyst was reused five times.
