Resumen:
Thermally stable zirconium pillared clays and sulfate modified zirconium pillared clays have been synthetized. Precise controlof the preparation parameters allows preparation of solids with controlled morphology, texture and acid properties. The preparation of a new type of split clay is discussed. introduction of sulfate in the pillar structure produces strongly acid pillared clays. The origin of acidity is discussed in each case.
