Zeolite nanoparticles are synthesized by hydrothermal method and Zeolite polypyrrole polymer nanocomposite is chemically polymerized. The structural, morphological, and chemical features of the Zeolite LTL/PPy material synthesized were investigated. The crystalline character of the materials may be seen in the powder XRD. The uniform hexagonal rod structure of the zeolite can be seen in SEM micrographs. In the case of the zeolite polypyrrole, SEM micrograph polypyrrole is encapsulating the zeolite; it is also observed that polypyrrole spherical balls are formed. The gas sensing substance is a polymer nanocomposite called Zeolite polypyrrole. The sensor can detect ammonia at a concentration of 1 ppm in less than a minute, with a response and recovery times of 15 and 35 seconds, respectively. The sensor has a sensitivity of 12.34 ppm-1. The polymer composite can degrade the methylene blue dye in the presence of UV light up to 79.4 %.
