چکیده

در این پژوهش نانو کامپوزیت روی اکسید آلاییده با نقره و سریم/پلی آنیلین(Ag-Ce-ZnO/PANI) به عنوان فوتوکاتالیست، برای تخریب هم­زمان دو آلاینده آلی پارانیتروفنول و متیلن بلو  در حضور نور فرا بنفش سنتز شد. آنالیزهای XRD ، FESEM و UV-Vis برای تعیین ویژگی­های فیزیکی، شیمیایی و اپتیکی نمونه­ های سنتز شده  مورد استفاده قرارگرفت. آزمایش ­های فوتوکاتالیستی نشان از عملکرد بهتر نانوکامپوزیت Ag-Ce-ZnO/PANI درمقایسه با سایر نمونه­ ها داشت. نتیجه­ ها نشان داد که با گذشت 60 دقیقه از آزمایش، حدود 88 % متیلن بلو و  56 % پارانیتروفنول توسط این نانوکامپوزیت تخریب شده است. عملکرد خوب فوتوکاتالیستی برای نانوکامپوزیت Ag-Ce-ZnO/PANI را می­توان به کاهش بازترکیب الکترون ـ حفره، افزایش هدایت الکتریکی و افزایش جذب  نسبت داد. فعالیت فوتوکاتالیستی پایدار و  کارآمد نانوکامپوزیت تهیه شده آن را به عنوان یک فوتوکاتالیست مؤثر در تخریب آلاینده های آلی به صورت تکی یا هم زمان معرفی می­ کند.
