Abstract :
در اين مقاله ابتدا نانوذرات Fe3O4با روش سونوشيمي سنتز شد. در مرحله دوم پوسته ي هيروكسيد منيزيم در اطراف هسته ي Fe3O4 قرار گرفتند. براي سنتز Fe3O4-MgO نمون در دماي 400 درجه سانتي گراد به مدت دو ساعت كلسينه شد. براي بررسي محصولات به دست آمده از پراش پرتو ايكس (XRD)، طيف سنجي مادون قرمز (FT-IR) ، ميكروسكوپ الكتروني پويشي((SEM و مغناطيس سنج ارتعاشي (VSM) استفاده شد. ويژگي فوتوكاتاليستي Fe3O4-Mg(OH)2 براي تخريب متيل اورانژ مورد بررسي قرار گرفت. نتايج نشان داد كه اين نانوساختار داراي خواص فوتوكاتايستي و مغناطيسي مناسبي مي باشد.
Abstract :
In this work firstly Fe3O4 nanoparticles were synthesized via a
sono-chemical method. At the second step magnesium hydroxide
shell was synthesized on the magnetite-core under ultrasonic
waves. For preparation Fe3O4-MgO the product was calcinated at
400 ?C for 2h. Properties of the product were examined by X-ray
diffraction pattern (XRD), scanning electron microscope (SEM)
and Fourier transform infrared (FT-IR) spectroscopy. Vibrating
sample magnetometer (VSM) shows nanoparticles exhibit super-
paramagnetic behavior. The photo-catalytic behavior of Fe3O4-
Mg(OH)2 nanocomposite was evaluated using the degradation of a
methyl orange (MeO) aqueous solution under ultraviolet (UV) light
irradiation. The results show that Fe3O4-Mg(OH)2 nanocomposites
have applicable magnetic and photo-catalytic performance.
