| Resumen en inglés | In this work, the comercial zeolites ZSM-5 and Y were submitted to previous ionic change with NH4NO3, followed by the addition of Nb. The incorporation of Nb on its structure aims increasing the acidity and improved the catalyst activity of these zeolites. The materials obtained are characterized by X-Ray diffraction patterns, chemical analysis, SEM and textural analysis by N2 adsorption. Furthermore, the materials were avaliated by decomposition reaction of the H2O2. The Nb presence improved the catalytic activity for H2O2 decomposition. Moreover, high amounts of Nb incorporated into zeolites caused a partial destruction of the structure of the materials as evidenced by X-Ray diffraction patterns. |
