Zeolites have been shown to have a large number of technological applications, especially in the formation of nanostructures inside them. This work evaluates the Zn concentration in an A4 zeolite for the formation of nanoparticles by ion exchange, by monitoring the temperature parameters. XRD and FT-IR analysis was carried out to verify that the zeolite structure was not affected and by UV-vis and SEM-EDS we analyzed which of the concentrations would be the most convenient. Taking as criteria the optimum ion exchange and the stability of zeolite A4).
