Journal Article 2024 02 03 The Nano-CrY zeolite synthesized and characterized by Fourier transfer infrared (FT-IR), X-ray diffraction (XRD),and Scanning electron microscopy (SEM).The result show that nano catalyst prepared with mainly particles size about 30-80 nm .The XRD show the structure of the zeolite does not collapse. This Nano-CrY zeolite has been used as new, and nontoxic catalyst for catalyzes of synthesis of 2-aryl-1H-benzothiazoles at mild condition . This procedure is simple, effective, inexpensive and green. The products were obtained in high yields and the catalyst is reusable. Since products were obtained by aqua work-up in good purity and complex purification methods are not necessary.
