• Studies on the synthesis and characterization of zeolite-LTL/PPy composite for gas sensing application

Zeolite nanoparticles are synthesized by hydrothermal method, and zeolite polypyrrole polymer nanocomposite is chemically polymerized. The polymer nanocomposite of zeolite polypyrrole is used as the gas sensing material.The sensor can detect the ammonia of the lowest concentration of 1 ppm with a response and recovery time of less than a minute. The sensor has a sensitivity of 12.34 ppm$^{-1}$. The polymer composite can also degrade the methylene blue dye inthe presence of UV light up to 79.4%. The powder X-ray diffraction of the materials shows the crystalline nature. The scanning electron microscope micrograph of the zeolite shows the regular hexagonal rod structure having an averagelength of 77.64 nm and diameter of 23.52 nm. In the case of the zeolite polypyrrole SEM micrograph, polypyrrole is encapsulating the zeolite, and also shows the polypyrrole spherical balls.
