چکیده
یکی از مهم‌ترین مشکلات زیست‌محیطی پالایشگاه‌های نفت، وجود انواع ترکیبات آلی آلاینده در پساب‌های خروجی آن‌هاست. یکی از مؤثرترین روش‌ها برای تصفیة این پساب‌ها و حذف آلاینده‌های آلی، استفاده از فرایندهای فوتوکاتالیستی است. در این تحقیق به‌منظور بهبود عملکرد فوتوکاتالیست نیمه‌هادی ZnWO4 تحت تابش نور مرئی، کامپوزیت نامتجانس آن با NiCo2S4 تهیه شد. این نانوکامپوزیت‌های نامتجانس با استفاده از نانومیله‌های ZnWO4 و نانوذرات NiCo2S4، به روش هیدروترمال تولید شدند. برای مشخصه‌یابی نمونه‌های تهیه‌شده، از پراش پرتو ایکس (XRD)، میکروسکوپ الکترونی روبشی نشر میدانی (FESEM)، طیف‌سنجی انعکاسی نفوذی (DRS) و فوتولومینسانس (PL) استفاده شد. نتایج نشان داد که نانوکامپوزیت نامتجانس ZnWO4/NiCo2S4 حاوی 20 درصد وزنی NiCo2S4، بهترین عملکرد فوتوکاتالیستی را از خود نشان می‌دهد. در این نمونه، 90 درصد آلاینده‌های آلی طی 2 ساعت تخریب شدند. همچنین، نتایج نشان داد که کامپوزیت کردن این نیمه‌هادی‌ باعث افزایش جذب نور مرئی، کاهش گاف انرژی و کاهش بازترکیب الکترون-حفره شده است و این پدیده، منجر به افزایش بازده فوتوکاتالیستی در تخریب آلاینده‌های آلی از طریق تولید مؤثرتر رادیکال‌های اکسیدکننده، مانند هیدروکسیل و سوپراکسید می‌شود.

چکیده English

One of the main challenges faced by oil refinery industries is the presence of various organic compounds as environmental pollutants in their effluents. Among the most effective methods for treating this type of wastewater and degrading organic pollutants is photocatalysis. In this study, to improve the photocatalytic performance of the ZnWO₄ semiconductor under visible-light irradiation, a heterojunction composite of ZnWO₄ and NiCo₂S₄ was prepared. The heterojunction nanocomposites were synthesized using a hydrothermal method with ZnWO₄ nanorods and NiCo₂S₄ nanoparticles. The nanocomposites were characterized by X-ray diffraction (XRD), diffuse reflectance spectroscopy (DRS), field-emission scanning electron microscopy (FESEM), and photoluminescence (PL) analyses. The results showed that the ZnWO₄/NiCo₂S₄ heterojunction nanocomposite containing 20 wt% NiCo₂S₄ exhibited the best photocatalytic performance. Furthermore, the results demonstrated that the enhanced photocatalytic performance resulted from a decrease in the band gap energy, increased visible-light absorption, and reduced electron–hole recombination, which promoted the more efficient generation of oxidizing radicals such as hydroxyl and superoxide radicals.
