This work describes the synthesis and characterization of mixed Al/Co pillared clays. The materials were prepared using different Co concentrations: 10%, 25%, 50%, 75% and 100%. The samples were analyzed by XRD, N2 physisorption, chemical analysis (AA), 27Al NMR, FTIR and EPMA. The use of small amounts of Co (10% and 25%) resulted in the formation of pillared clays, and the material containing 25%...
