En el presente trabajo se sintetizaron por el mtodo solgel, una serie de soportes catalticos con base en xidos de circonio (ZrO2) modificados por la presencia de agentes cidos tales como iones sulfatos (SO42), fosfatos (PO43) y un heteropolianin ([PW12O40]3). El inters principal de esta investigacin radic en estudiar el efecto de los agentes dopantes sobre las propiedades trmicas, texturales, estructurales y cidas del ZrO2, as como analizar su actividad cataltica en la isomerizacin de hidrocarburos de cadena corta (C5C6), debido a que esta reaccin representa una alternativa en la obtencin de combustibles con alto nmero de octano. Para ello, los materiales sintetizados se caracterizaron mediante anlisis trmicos, difraccin de rayos X, fisisorcin de nitrgeno, espectroscopa de infrarrojo, termodesorcin programada de amoniaco, termodesorcin programada de nbutilamina, titulacin potenciomtrica con nbutilamina, deshidratacin de 2propanol y adsorcin de piridina analizada por espectroscopa de infrarrojo. La actividad cataltica de los xidos de circonio acidificados se evalu en la isomerizacin de npentano y nhexano a 250C y presin atmosfrica.
