عنوان انگلیسی Formation and characterization of zeolite Y-platinum nanoparticles by rapid method of ultrasonic irradiation and investigation of its electrochemical property
چکیده انگلیسی مقاله Zeolite has presented a unique crystalline structure with an excellent exchange capability formed by Al-O-Si, which it can be used as a good surface for dispersed metal particles. In this work, rapid synthesis of zeolite Y-platinum nanoparticles by ultrasonic treatment was studied. The structure and morphology of the prepared zeolite Y-platinum nanoparticles were characterized using X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), Scanning electron microscopy (SEM), Transmission electron microscopy (TEM), Energy-dispersive X-ray spectroscopy (EDS), Brunauer-Emmett Teller (BET), and EDS mapping analysis. In this work, we successfully developed a rapid and green method for the synthesis of zeolite Y and zeolite Y-platinum nanoparticles with uniform small crystals and high purities by the use of ultrasonic irradiations. The use of ultrasound irradiation has proved to be an environmentally sound, time and cost effective approach for various organic and inorganic compounds. Also, it is an excellent technique for the adherence of nanoparticles to a large variety of substrates. Investigation of the electrochemical characteristics of the prepared Z-Y-Pt NPs was carried out by the use of cyclic voltammetry (CV) test and it displays ratio of jf/jb=1.10 that can be suitable for redox reaction in fuel cell.
