Efecto del Au en la hidrogenación de Citronelal sobre catalizadores Ir/TiO2

Hugo Alfonso Rojas Sarmiento, José Jobanny Martínez Zambrano, Diana Clemencia Guerrero Araque

Resumen

Se estudió la hidrogenación en fase líquida del citronelal usando catalizadores Ir, Au, and Ir-Au. Los catalizadores bimetálicos fueron preparados por deposito-coprecipitación con urea (CDPU). Los catalizadores fueron reducidos a 573 y 773 K, y caracterizados mediante EDX, XRD, fisisorción de N₂ y quimisorción de H₂a 303 K. Los resultados indicaron que las propiedades texturales de los catalizadores soportados no cambian respecto al metal, mientras que la disociación de H₂ varía dependiendo del metal soportado. Para los catalizadores Ir-Au/TiO₂ un incremento en la temperatura de reducción favorece la conversión del citronelal, sin embargo, disminuye la selectividad hacia el alcohol insaturado.
