Abstract

Arcillas modificadas con Al-Cu fueron sintetizadas a partir de una bentonita colombiana variando la relación molar Cu/Al y la temperatura de hidrólisis. Los sólidos obtenidos fueron caracterizados por absorción atómica (AA), capacidad de intercambio catiónico residual (CIC) y difracción de rayos X (DRX). La oxidación de fenol en medio acuoso fue empleada para evaluar la actividad catalítica. Las arcillas obtenidas exhiben interesantes comportamientos catalíticos bajo condiciones moderadas (temperatura ambiente y presión atmosférica) sin lixiviación metálica considerable. El mejor comportamiento catalítico fue obtenido en los sólidos con más baja relación Cu/Al preparados a temperatura ambiente en la hidrólisis.
