El presente trabajo tiene la finalidad de realizar el estudio del comportamiento catalítico de un material súper-ácido el cual es zirconia sulfatada soportada en dos materiales mesoporosos con área específica considerable como son MCM-41 y SBA-16. Ambos sólidos fueron caracterizados por DRX, fisisorción de y SEM-EDS. Para comparar la actividad catalítica se realizó en una reacción de apertura nucleofílica de un epóxido con anilina para la obtención de un β-aminoalcohol. In the this work mineral zeolitic samples was analyzed, in powder form and heat treated 250, 350 and 500 ° C, respectively, which are of particular interest due to their catalytic properties. The treatment process consists of mechanical grinding of solid samples, process conducted for 3 hours, subsequently calcining the sample for 4 hours. The structural characterization of the materials was carried out by XRD, while morphology was determined by SEM and width bandgap materials by using RD-UV-Vis and Kubelka-Munk transform. Photo-degradation reaction of textile compound called, reactive black 5 dye (RB-5) was carried out in a batch reactor with a white light lamp of λ = 570 nm, ambient temperature and pressure; the kinetics of degradation reaction was monitored by checking the variation on absorption band (λ = 595 and 310 nm) with UV -Vis spectroscopy.
