Structural, optical, thermal and Photocatalytic properties of ZnO nanoparticles of Betel Leave by using Green synthesis method

در اين مطالعه سنتز سبز نانوذرات اكسيد روي با استفاده از عصاره برگ بتل و استات روي بررسي شد. ذرات اكسيد روي عامل دار شده با برگ بتل از طريق پراش پرتو X، ميكروسكوپ الكتروني انتشار ميداني، فوتولومينسانس و اناليزهاي حرارتي مورد بررسي قرار گرفت. نتايج نشان داد ساختار بلوري نانوذرات هگزاگونال و اندازه آن ها 50 نانومتر مي باشد. مطالعات فوتولومينسانس نشر رنگ آبي در زول موج 463 نانومتر را تاييد كرد. كاربرد فوتوكاتاليستي براي تخريب متيلن بلو تحت نور خورشيد با نانوذرات سنتز شده بررسي گرديد. واژگان كليدي: آناليز شناسايي، سنتز سبز، SEM، مواد انرژي خورشيدي، ZnO-NPs

In this present study reports the green synthesis of zinc oxide nanoparticles using Betel leaf extracts and zinc acetate. Te functionalization of ZnO particles through Betel leaf extract mediated bio reduction of ZnO was investigated through X-ray difraction, Field emission scanning electron microscopy, photoluminescence, thermal gravimetric-diferential thermal analysis, hexagonal shaped ZnO-nanoparticles with size about 50 nm were synthesized and characterized using X-ray difraction analysis. Te diameter of the nanoparticles in the range of 50 nm was found from scanning electron microscopy study. Photo luminescence study reveals the blue emission at 463nm respectively. hermal gravimetric- diferential thermal analysis show that the observed at 480o C, indicating that no decomposition occurs above this temperature. Te photocatalytic degradation of methylene blue dye was examined using ZnO nanoparticles under solar as well as ultra violet light irradiation of the MB dye. Te method stands out primarily due to the fact that it is eco-friendly and shuts down the demerits of conventional physical and chemical methods. Tese particles are anticipated to have extensive applications in various industries.
