چکیده: (1583 مشاهده)
نانو¬کامپوزیت MoS2/Ag2S از سنتز سبز نانوذرات Ag به روش گرمابی و بدون استفاده از جو بی¬اثر تهیه شد. نمونه¬های سنتزشده با استفاده از پراش¬سنج ¬پرتو ایکس (XRD)، طیف¬سنج تبدیل فوریه فروسرخ (FT-IR)، میکروسکوپ الکترونی روبشی (SEM) و میکروسکوپ الکترونی عبوری (TEM) مشخصه¬یابی شدند. ویژگی¬های نوری نمونه¬ها با استفاده از طیف¬سنج جذبی UV-Vis بررسی گردیدند. الگو‌های (XRD) تشکیل ساختارهای ششگوشی MoS2 و تک¬میل Ag2S را تایید کرد. تصاویر SEM و TEM ریخت‌شناسی و بارگیری Ag2S بر ساختار MoS2 را نشان دادند. فعالیت فوتوکاتالیزوری نانو¬کامپوزیت با استفاده از رنگ¬های متیل اورانژ و متیلن‌بلو با تابش نور رابنفش مورد ارزیابی شد. نتایج نشان داد که نانو¬کامپوزیت MoS2/Ag2S مخرب خوب رنگ¬های متیل اورانژ و تاحدی متیلن¬بلو با تابش نور فرابنفش است.
