The alumina-pillared synthetic boron-containing saponite [designated as AI-PSBCS(X),X is the added boron moles that are based on Mg=6 moles in the preparation] possessed both higher cumene dealkylation activity [93.4 wt.%] and better benzene selectivity [74.0 wt. %] than alumina-pillared non-boro

Nonuniform pillar distributions have been attributed to layer charge heterogeneity and to pillar deformation. Other defects, like stacking faults,

In the literature, a polyoxometalate of transition metals, such as molybdenum, tungsten, or vanadium, was usually the subject to introduce into the interlayer space of anionic clays. However, the composition of these polyoxometalates is pH dependent, and these
