What are zeolites? Zeolites are microporous crystals, typically consisting of the elements of Earth’s crust: silicon, aluminium and oxygen, what makes them strong materials - in essence nanoporous rocks. Their pores are of molecular dimensions thereby providing size and shape selectivity for guest molecules. Zeolites are formed from SiO44- and AlO45- tetrahedra linked through the shared oxygen atoms. Thus formed rigid... More
