I-Zeolite ye-molecular sieves inefuthe elinamandla lokuhlukana kwi-nitrogen kunye ne-oxygen.Inesakhiwo kunye neempawu zekristale, umphezulu yi-skeleton eqinile, kwaye imingxuma yangaphakathi inokudlala indima ye-adsorbing molecules.Kukho iipores ezidityaniswe omnye komnye phakathi kwemingxuma, kwaye iimolekyuli zidlula kwiipores.Ngenxa yobume obucocekileyo bee-pores, ukusabalalisa ubungakanani be-pore ye-molecular sieve ifana kakhulu.Iisefu zeemolekyuli zikhetha ngokukhetha iimolekyuli ezisekwe kubungakanani beepore ngaphakathi kweekristale zazo, oko kukuthi, iimolekyuli ze-adsorb zobungakanani obuthile ngelixa zigxotha iimolekyuli zezinto ezinkulu.
