چکیده
این پژوهش بر سنتز موفق نانوکامپوزیت Fe0.5V3.5O8/rGO از طریق یک روش سونوشیمی ساده تمرکز دارد. نتایج مشخصه‌یابی ساختاری نشان داد که فاز Fe0.5V3.5O8/rGO (دارای ساختار اورتورومبیک) با احیای کامل گرافن اکساید (GO) به گرافن اکساید کاهش یافته rGO)) در نمونه‌ی نهایی تشکیل شده است. تصاویر میکروسکوپی تأیید کردند که حضور rGO باعث بهبود قابل توجه مورفولوژی، کاهش اندازه ذرات و پراکندگی یکنواخت آن‌ها بر روی صفحات گرافن شده است. بررسی خواص نوری توسط طیف‌سنجی، یک انتقال به سرخ قابل توجه و کاهش شکاف نوار از eV 2 به eV 6/1را در نانوکامپوزیت نشان داد که قابلیت جذب آن در ناحیه نور مرئی را به شدت افزایش داده است. ارزیابی فوتوکاتالیزوری در تخریب متیلن بلو (MB) تحت تابش نور مرئی توسط لامپ 400 وات اسرام به مدت 30 دقیقه نشان داد که نانوکامپوزیت با راندمان 81%‎، به دلیل جذب سطحی بهتر و خواص نوری تقویت‌شده، عملکرد بسیار بالاتری نسبت به اکسید فلزی خالص دارد. داده‌های تجربی نشان دادند که واکنش از مدل سینتیکی مرتبه صفر پیروی می‌کند و ضریب همبستگی بالای R2 = 0.96 به‌دست آمد. این نتایج بیانگر کارایی نانوکامپوزیت Fe0.5V3.5O8/rGO در حذف MB است.

چکیده English

This research focuses on the successful synthesis of the Fe0.5V3.5O8/rGO nanocomposite through a simple sonochemical method. Structural characterization results indicated that the Fe0.5V3.5O8/rGO phase (with an orthorhombic structure) was formed in the final sample by the complete reduction of GO (graphene oxide) to rGO (reduced graphene oxide). Microscopic images confirmed that the presence of rGO significantly improved the morphology, reduced the particle size, and resulted in their uniform dispersion on the graphene sheets. Optical properties analysis by DRS spectroscopy showed a noticeable red shift and a reduction in the bandgap from 2 eV to 1.6 eV in the nanocomposite, which drastically increased its absorption capability in the visible light region. Photocatalytic evaluation in the degradation of methylene blue (MB) under visible light irradiation using a 400 W Osram lamp for 30 minutes revealed that the nanocomposite achieved a degradation efficiency of 81%. This superior performance is directly attributed to enhanced surface adsorption and improved optical properties, compared to the pure metal oxide. Experimental data indicated that the reaction follows a zero-order kinetic model, with a high correlation coefficient of R2 = 0.96. These results demonstrate the efficiency of the Fe0.5V3.5O8/rGO nanocomposite in the removal of MB.
