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 porous transition metal oxides of various types, also including porous pillared interlayer materials that have either positive or negative charges. This review is not all-inclusive: it only covers the most recent papers published from about January 1995 to the present. A discussion of new transition metal oxides, porous pillared materials, sulfide layered materials and porous phosphates is included. Zeolites, isomorphous substitution of zeolites, aluminophosphates, and silicoaluminophosphates will not be covered since excellent reviews can be found 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 concerns pillared materials, including layers that are anionic as well as cationic. Sulfide systems discussed in a further section are primarily layered phases. The final section concerns porous phosphate materials. (C) 2000 Elsevier Science B.V. All rights reserved.
