PtxNiy alloy nanoparticles with different compositions were prepared on Carbon Nanotube (CNT) surfaces in the presence of amine-terminated poly(amido amine) dendrimer as a scaffold. PtxNiy alloys with an average diameter of 2–3 nm were uniformly deposited on dendrimer bound on CNT. The formation of the PtxNiy alloys and the presence of Pt(0), Ni(0), Ni(OH)2 and NiOOH were revealed from X-ray diffraction and X-ray photoelectron spectroscopic results. The total metal content in the PtxNiy alloys increased with increasing the supplied Ni precursor, and the addition of Ni to Pt could lead the alloy formation with high thermal stability. It should be noted that the bimetallic nanoparticles with Ni up to 20 wt% showed efficient catalytic activity for methanol oxidation in proportion to Pt catalyst. This study demonstrates the promising alternative for the high demand of Pt in the cathode catalysts of direct methanol fuel cells.

PtxNiy alloy nanoparticles with different compositions were prepared on Carbon Nanotube (CNT) surfaces in the presence of amine-terminated poly(amido amine) dendrimer as a scaffold. PtxNiy alloys with an average diameter of 2–3 nm were uniformly deposited on dendrimer bound on CNT. The formation of the PtxNiy alloys and the presence of Pt(0), Ni(0), Ni(OH)2 and NiOOH were revealed from X-ray diffraction and X-ray photoelectron spectroscopic results. The total metal content in the PtxNiy alloys increased with increasing the supplied Ni precursor, and the addition of Ni to Pt could lead the alloy formation with high thermal stability. It should be noted that the bimetallic nanoparticles with Ni up to 20 wt% showed efficient catalytic activity for methanol oxidation in proportion to Pt catalyst. This study demonstrates the promising alternative for the high demand of Pt in the cathode catalysts of direct methanol fuel cells.
