A universal method for preparing highly dispersed bimetallic nanoparticles: the case of Pd–Fe

A new approach to the synthesis of highly dispersed deposited bimetallic Pd–Fe nanoparticles with a median size of 3–4 nm and a narrow size distribution has been developed, based on the use of metal acetylacetonates as starting materials. It has been established that Pd in the presence of Fe undergoes strong oxidation compared to monometallic nanoparticles. Comparison of the obtained results with data for other systems has shown the universality of the method for preparing highly dispersed palladium-based bimetallic nanoparticles.
