The field of zeolites has rapidly and continually evolved since the introduction of the first synthetic zeolites in the 1950s. A wave of research in the 1980s and 1990s launched the discovery of new framework structures and compositions, serving as adsorbents, ion exchangers and catalysts for the production of fuels and chemicals and for environmental protection. As of today, 204 unique zeolite framework types have been identified', although only a handful of them have been commercialized.
