Encapsulation of the iron oxide nanoparticles in the zeolite cages by ion exchange method which is accompanied by characterization and examination of the photocatalytic activity for phenol photodegradation are reported. The largest Fe exchanged and the lowest zeolite structural damaged can be obtained when the ion exchange was carried out at pH 7. The iron uptake by the zeolite may be formed as nanoparticles encapsulated in the zeolite cages and as iron oxide fine particles dispersed on the external surface that can be easily removed by EDTA solution. It is provided evident that the encapsulation of the iron oxide in the zeolite can increase their band gap energy (Eg) as a character of a photocatalyst and so their photocatalytic activity in the phenol photodegradation.
