= Molecular sieve
{wiki=Molecular_sieve}
A molecular sieve is a material with a porous structure that can separate molecules based on their size and shape. Typically composed of zeolites or other crystalline aluminosilicates, molecular sieves have tiny uniform pores that allow them to selectively adsorb smaller molecules while excluding larger ones. Key characteristics and applications of molecular sieves include: 1. **Adsorption**: Molecular sieves can adsorb gases or liquids, making them useful for drying and purification processes.
