Abstract:It is well known that Pt-Ru alloy exhibits a promising catalytic activity for fuel cells. In this work we present density functional theory (DFT) study of the randomly mixed Pt-Ru alloys and discussed its stability based on the relative position of Pt and Ru atoms. The structures are modelled as five layer slabs because the ratio of surface atoms comparable with that for clusters about 3 nm sizes. The top surface fully covered by the Pt atom exhibits highest stability compared with other randomly mixed Pt-Ru a… Show more
“…Mixed-metal nanosized systems based on ruthenium are widely used as heterogeneous catalysts. Nanoparticles and nanoalloys of Pd-Ru and Pt-Ru are well recommended in the electrochemical oxidation reactions [1][2][3][4][5] with potential for application in different fuel cells. The bimetallic systems of Co-Ru and the three-metal intermetallics based on the Heusler compound have great potential in the nitrogen activation reaction.…”
Heterometallic complex [RuNO(NO2)4OHNi(En)2] was prepared in the reaction of [RuNO(NO2)4OH]2- with Ni2+ in the presence of small excess of ethylenediamine. According to single crystal XRD the ruthenium fragment is coordinated...
