A review of zeolite-like porous materials

This review focuses on the most recent reports of zeolite-like microporous and mesoporous materials and in particular their synthesis. We focus on por ous transition metal oxides of various types, also including porous pillare d interlayer materials that have either positive or negative charges. This review is not all-inclusive: it only covers the most recent papers publishe d from about January 1995 to the present. A discussion of new transition me tal oxides, porous pillared materials, sulfide layered materials and porous phosphates is included. Zeolites, isomorphous substitution of zeolites, aluminophosphates, and sili coaluminophosphates will not be covered since excellent reviews can be foun d elsewhere [1,2]. The section on porous transition metal oxides focuses on both microporous and mesoporous transition metal oxides and, in particular , synthetic strategies used to produce new materials. The next section conc erns pillared materials, including layers that are anionic as well as catio nic. Sulfide systems discussed in a further section are primarily layered p hases. The final section concerns porous phosphate materials. (C) 2000 Else vier Science B.V. All rights reserved.
