WebZeolites are structures of crystalline solids that are made up of silicon, oxygen, and aluminium. These structures form a frame with cavities and channels within which cations, water, certain relatively small molecules can reside. It can be noted that zeolites are sometimes referred to as molecular sieves as well. WebZeolite scientists, whether they are working in synthesis, catalysis, characterization or application development, use theAtlas of Zeolite Framework Typesas a reference. It describes the main features of all of the confirmed zeolite framework structures, and gives references to the relevant primary structural literature.
