چکیده مقاله:

در این پژوهش، یک روش ساده و مفید برای تولید لایه¬ی نازک Pt/CdS و Pd/CdS به وسیله کاهش کمپلکس¬های آلی-فلزی PtCl2cod و PdCl2cod، ترانس-۱، ۵-سیکلو دی¬ان cod و کادمیم سولفید در سطح مشترک آب- تولوئن ارائه شده است. ساختار و ریخت¬شناسی نانوذرات سنتز شده به وسیله تکنیک¬های 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.


Article's English abstract:

In this study, a facile and useful procedure for the synthesis of Pt/CdS and Pd/CdS nanoparticles NPs thin films is presented by the reduction of PtCl2cod and PdCl2cod cod cis,cis-1,5-cyclooctadiene complexes at water- toluene interface. The structure and morphology of Pt/CdS and Pd/CdS NPs thin films were characterized by X-ray diffractin and transmission electron microscopy techniques. Catalytic activities of Pt/CdS and Pd/CdS nanostructures were investigated in the reduction of p-nitrophenol to p-aminophenol. Pt/CdS thin film shows a higher catalytic activity toward this reaction.
