چکیده

در این پژوهش، نانوساختارهای اکسید بیسموت خالص (Bi2O3) و نانوکامپوزیت‌های اکسید بسیموت- اکسید بیسموت مولیبدنیوم (Bi2O3/Bi2MoO6) با افزودنی مقادیر 2، 4، 6، 8، 10 وcc12 نمک مولیبدن (Na2MoO4.2H2O) به روش فراصوت تهیه شده و تأثیر میزان افزودنی آن بر فعالیت فوتوکاتالیستی اکسید بیسموت خالص، از طریق حذف متیلن بلو از آب آشامیدنی مورد مطالعه قرار گرفته است. ویژگیهای ساختاری، ریخت شناسی و خواص اپتیکی این نانوکامپوزیت‌ها، از طریق آنالیز حرارتی(TGA-DTA)، الگوی پراش پرتو ایکس (XRD)، میکروسکپی الکترونی روبشی(SEM) و طیف سنجی جذبی مرئی- فرابنفش (UV-Vis) مورد بررسی قرار گرفته است. نتایج حاصل از الگوی پراش پرتو ایکس نشان داد با افزایش میزان افزودنی نمک مولیبدن، از شدت قله‌های پراش اکسید بیسموت کاسته شده و قله‌های اکسید بیسموت مولیبدنیوم آشکارتر می‌شوند. تصاویر SEM نشان دهنده تغییر ریخت نانوکامپوزیت‌ها و اندازه آنها در اثر افزایش افزودنی نمک مولیبدن است. از طریق طیف جذبی مرئی- فرابنفش، مقدار گاف انرژی نانوکامپوزیت‌ها محاسبه شده و نتایج نشان داد که افزایش میزان نمک مولیبدن، موجب کاهش گاف انرژی نمونه‌ها شده است. همچنین نتایج بررسی فعالیت فوتوکاتالیستی نشان داد که نانوکامپوزیت حاوی cc 2 نمک مولیبدن با تخریب %100 متیلن بلو در مدت زمان 24 دقیقه، دارای بالاترین فعالیت فوتوکاتالیستی در بین نمونه‌های تهیه شده می‌باشد.

چکیده [English]

In this study, pure bismuth oxide (Bi2O3) nanostructures and bismuth oxide- molybdenum bismuth oxide (Bi2O3/ Bi2MoO6) nanocomposites with additive 2, 4, 6, 8, 10 and 12cc values of molybdenum precursor (Na2MoO4.2H2O) were prepared by ultrasound assisted-method, and the effect of additive values of molybdenum precursor has been studied on the photocatalytic activity of pure bismuth oxide nanostructures by removing methylene blue from the water. The structural, morphological and optical properties of these nanostructures have been investigated by TGA/DTA, XRD, SEM and UV-Vis analyzes. The results of XRD show that with increasing of additive values of molybdenum precursor, the intensity of bismuth oxide diffraction peaks decreases and the intensity of bismuth oxide molybdenum diffraction peaks becomes more apparent. SEM images show change in the nanocomposite’s morphology and their size due to additive of molybdenum precursor. The energy gap of nanocomposites was calculated by UV-Vis spectrum, and the results showed that, the energy gap of the samples has been reduced with increasing the amount of molybdenum precursor. Also, the results of photocatalytic activity showed that the nanocomposite containing 2cc molybdenum precursor has the highest photocatalytic activity among the prepared samples and removed 100% methylene blue from the water within 24 minutes.
