چکیده مقاله:
Zeolites are inorganic crystalline aluminosilicates with a network of pores classified as micro porous materials. Their micro pore topology, well-proportioned surface functionality, and high stability have led to the application of zeolites in catalysis, molecular separation, and water treatment [1]. Recently, the use of ultrasonic irradiation has been extensively studied, as a new source of energy and environmentally compatible [2]. There are reports about the use of ultrasound in many areas such as sonocatalysis, preparation of materials, polymer chemistry, organic chemistry, extraction, enzymatic catalysis, electrochemistry, biomass conversion, environmental remediation [3]. Also, platinum is a noble and expensive metal with high catalytic activity and stability that has many technological applications. In this work, first zeolite Y was prepared by ultrasonic method and then platinum nanoparticles were deposited on the surface of zeolite Y using ultrasonic irradiation. The structure and morphology characteristics of the product were investigated by Fourier transform infrared (FT‐IR), X‐ray diffraction (XRD), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). Figure 1 shows SEM and TEM images of the synthesized zeolite Y-platinum nanoparticles.
