A catalyst for a fuel cell anode comprises an alloy of Pd and at least two other transition metals, at least one of which which binds to hydrogen and/or carbon monoxide at least as strongly as Pd does. Suitable transition metals which bind more strongly are Co, W, Ti, V, Cr, Fe, Mo, Nb, Hf, Ta, Zr and Re. PdCoW is the most preferred alloy. The catalyst is used on the anode of a hydrogen oxidising fuel cell, such as a PEMFC to catalyse the hydrogen oxidation reaction.

The present disclosure relates to metal alloys for biosensors. An electrode is made from ruthenium metal or a ruthenium-based alloy. The resulting electrode has physical and electrical property advantages when compared with existing pure metal electrodes.

The present invention is drawn to a medical Pt alloy wire, made of a Pt—W alloy containing 10% by mass or more and 15% by mass or less of W, a balance of Pt, and inevitable impurities. The Pt alloy wire has Vickers hardness of 400 Hv or more and 600 Hv or less, and has hardness and strength superior to those of a conventional Pt alloy wire having the same composition. The Pt alloy wire of the present invention has properties preferable as a coil applied to an embolic coil or a guide wire or the like, and is also good in workability in secondary processing for producing such a medical tool.

Presented is a selective hydrogenation catalyst and a method of making the catalyst. The catalyst comprises a carrier containing bi-metallic nanoparticles. The nanoparticles comprise a silver component and a palladium component. The catalyst is made by incorporating an aqueous dispersion of the bi-metallic nanoparticles onto a catalyst carrier followed by drying and calcining the carrier having incorporated therein the dispersion. The catalyst is used in the selective hydrogenation of highly unsaturated hydrocarbons contained olefin product streams.
