Abstract

Au-Ag stable bimetallic nanoparticles were synthesized by a microwave assisted route, by using an eco-friendly method that provided a total reaction yield. Both UV-VIS spectroscopy and microscopy data confirmed the formation of bimetallic nanostructures, in the form of core-shell or alloy. Catalytic tests showed that prepared nanostructure of Au, Ag and AuAg act as effective catalyst in the hydrogenation of p-nitrophenol, resulting in agreement with literature data, but with a decreased activity for higher silver content. The best colouring performance was observed for Ag-Core samples, further analysis are ongoing to explain the reasons of this behavior.
