چکیده

در این پژوهش، یک روش ساده و مفید برای تولید لایه‌ی نازک Pt/CdS و Pd/CdS به وسیله کاهش کمپلکس‌های آلی-فلزی PtCl2cod و PdCl2cod، ترانس-۱، ۵-سیکلو دی‌ان cod و کادمیم سولفید در سطح مشترک آب- تولوئن ارائه شده است. ساختار و ریخت‌شناسی نانوذرات سنتز شده به وسیله تکنیک‌های تفرق اشعه ایکس XRD و میکروسکوپ الکترونی عبوری TEM مورد بررسی قرار گرفتند. فعالیت‌های کاتالیزوری نانو‌ساختار‌های Pt/CdS و Pd/CdS در واکنش کاهش پارا‌-نیترو‌فنول به پارا-آمینو‌فنول مورد بررسی قرار گرفتند.
