چکیده [English]

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.
