Organic nanoparticles were deposited on LTA, ZSM5, FAU, clinoptilolite zeolites and montmorillonite clay forming a group of hybrid materials. The nanoparticles were analyzed by GC-Mass and proceed from the active phase of a plant constituted by 1.2 benzenedicarboxylic acid (66.1%), mono (2 ethilester) (66.1%), hexadecanoic acid (74.9%), and Y-isosterol (81.4%). Each of the hybrid materials was characterized by XRD, SEM and EDS. Additionally; the materials obtained were analyzed by high resolution adsorption (HRAD). The N2adsorption isotherms at 76 K obtained in the presence or absence of nanoparticles showed an Ia character for (LTA, FAU and ZSM5) synthetic zeolites, whilst (clinoptilolite) natural zeolite and clay (montmorillonite) showed a type II-IV character. The adsorption capacity of these substrates was analyzed by means of the Lagnmuir, de Boer, and Gursvitch rule approachs. The supermicropores present were measured by the NLDFT approach. The results indicated that the growth of nanoparticles in zeolites resulted in the emergence and opening of emerging pores of different geometry. However, in the case of ZSM5 and LTA zeolites their porosities were blocked by the nanoparticles.
