I-Zeolite ye-molecular sieves zinefuthe elinamandla lokwahlula kwinitrogen kunye neoksijini.Inesakhiwo kunye neempawu zekristale, umphezulu we-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 ze-adsorb esekwe kubungakanani bemibhobho engaphakathi kwiikristale zazo, oko kukuthi, iimolekyuli ze-adsorb zobungakanani obuthile ngelixa zigxotha iimolekyuli zezinto ezinkulu.
