چکیده
در این مطالعه نانوکامپوزیت پلی‌اکسومتالات-تیتانیم دی‌اکسید (SiW11-TiO2)با استفاده از روش گرمآبی سنتز و با روش‌های FT-IR، XRD، FE-SEM/EDS، BET و TEM ،مشخصه‌یابی شد. سپس عملکرد این نانوکامپوزیت به عنوان یک نانوفوتوکاتالیزور در تخریب رنگینه‌هایDR 23 وDB 166 تحت شرایط مختلف شامل مدت زمان تابش، مقدار فوتوکاتالیزور، غلظت محلول رنگینه و pH تحت تابش نور مرئی لامپ سدیم و نور خورشید بررسی شد. نتایج نشان داد که این فوتوکاتالیزور قادر است با استفاده از 10 میلی‌گرم از آن در pH اسیدی و طی 30 دقیقه، این رنگینه‌ها را به مقدار قابل توجهی تخریب کند بطری که میزان تخریب رنگینه در حضور نور خورشید افزایش چشمگیری داشت. بررسی سینتیک واکنش تخریب نشان داد که این فرآیند از نوع شبه مرتبه اول است. علاوه بر این، نتایج آزمایش-ها نشان داد که نانوکامپوزیت SiW11-TiO2 فعالیت فوتوکاتالیزوری بالاتری نسبت به SiW11 دارد. این نانوکامپوزیت نه تنها توانایی تخریب کامل رنگینه‌های آزو را دارد، بلکه پایداری و قابلیت استفاده مجدد تا 12 بار و عملکرد مؤثر در نمونه‌های حقیقی را نیز از خود نشان داد.

چکیده English

In this study, the polyoxometalate-titanium dioxide nanocomposite (SiW11-TiO2) was synthesized using the hydrothermal method and characterized by FT-IR, XRD, FE-SEM/EDS, BET, and TEM techniques. The performance of this nanocomposite as a nanophotocatalyst was then investigated for the degradation of the dyes DR 23 and DB 166 under various conditions, including irradiation time, photocatalyst dosage, dye solution concentration, and pH, under visible light from a sodium lamp and sunlight. The results demonstrated that this photocatalyst, using only 10 mg at acidic pH and within 30 minutes, could significantly degrade these dyes, with a marked increase in degradation efficiency under sunlight. The kinetic study of the degradation reaction indicated that the process follows pseudo-first-order kinetics. Additionally, experimental results revealed that the SiW11-TiO2 nanocomposite exhibited superior photocatalytic activity compared to SiW11 alone. This nanocomposite not only has the capability to completely degrade azo dyes but also demonstrated stability and reusability up to 12 cycles and effective performance in real sample applications.
