A molecular sieve (also known as synthetic zeolite) is a kind of aluminosilicate microporous net-like crystal material, composed of SiO2 and Al2O3 tetrahedrons, with uniform pore size (about a few angstroms) and a huge specific surface area. There are metal cations (such as Na+, K+, Ca2+, etc.) in the molecular sieve lattice to balance the excess negative charges in the tetrahedron. Different types of molecular sieves have different pore sizes or shapes and can be used to separate various molecules.
