The conjunction of the PdSn alloy and SnO2 is of interest for improving catalytic activity in formic acid oxidation (FAO). Here, we report the synthesis of PdSn-SnO2 nanoparticles and a study of their catalytic FAO activity. Different degrees of interfacial contact between SnO2 and PdSn were obtained using two different stabilizers (sodium citrate and EDTA)… (More)
The design of amorphous noble metallic nanoparticle electrocatalysts is an important fundamental and applied research challenge because their surface is rich in low-coordination sites and defects which could act as the active sites in various catalytic processes. Here we describe new findings on the amorphous platinum-nickel-phosphorous nanoparticles… (More)
Two structural forms of a ternary alloy PtRuIr/C catalyst, one amorphous and one highly crystalline, were synthesized and compared to determine the effect of their respective structures on their activity and stability as anodic catalysts in methanol oxidation. Characterization techniques included TEM, XRD, and EDX. Electrochemical analysis using a glassy… (More)
NixCoy alloy pompoms formed by the aggregation of nano ultrathin sheets were prepared by simultaneous reduction of NiCl2 and CoCl2 with NaBH4via a liquid-liquid interface reaction. Ni1Co3 pompoms produced markedly higher activity and stability as hydrazine oxidation catalysts than Ni, Co and other NixCoy pompom catalysts.
