Beta zeolite is a type of crystalline aluminosilicate material known for its high surface area, unique pore structure, and strong acidity. It belongs to the family of zeolites, which are microporous materials widely used in catalysis, ion exchange, and adsorption applications. Beta zeolite's three-dimensional structure consists of interconnected pores and channels that allow for selective diffusion of molecules, making it a valuable material in various catalytic processes.
