Abstract

In the present study, silver nanoparticles (AgNPs) have been prepared by reduction of silver salts using NaBH4 as reducing agent and polyvinylpyrrolidone (PVP) as stabilizing agent. Formation of AgNPs is characterized by UV-visible spectroscopy and TEM analysis. Ruthenium nanoparticles (RuNPs) have been prepared by reduction of ruthenium salts using microwave assisted glycol reduction method and PVP is used as stabilizing agent. Formation of RuNPs is characterized by TEM analysis and diffused reflectance spectra. The AgNPs and RuNPs thus formed have been used for the preparation of Ag-Ru bimetallic nanoparticles by subsequent stirring and sonication. The catalytic activity of these nanoparticles are tested by the model reaction of reduction of 4-nitrophenol to 4-aminophenol. 4-Nitrophenol is not reduced directly by NaBH4. Metal nanoparticles interact with molecular hydrogen produced from NaBH4 and produce active hydrogen, which reduces 4-nitrophenol. The reaction was monitored by UV-visible spectroscopy. The reduction follows first order kinetics.
