If drying at supercritical conditions is replaced by air drying (AD), the clays lose their macroporosity, and in the case of montmorillonite, a large decrease i

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

Dominique René Fara,Sibylle Olbert-Bocknt, the Si-Si and the Si-H bonds of the siloxene were oxidized to Si-O-Si and Si-OH bonds, respectively, and the interlayers were cross-linked by the condensation of the Si-OH groups. The resulting compounds have high surface areas (400–600 m./g) with pores in the micropore to mesopore ranges. The c
