Patent · Tue Nov 10 00:00:00 EST 2020

OSTI ID:1771617

Stamenkovic, Vojislav; Krumdick, Gregory K.; Wang, Rongyue; Markovic, Nenad; Pupek, Krzysztof Z.

A method for scaled-up synthesis of PtNi nanoparticles. Synthesizing a Pt nanoparticle catalyst comprises the steps of: synthesizing PtNi nanoparticles, isolating PtNi/substrate nanoparticles, acid leaching the PtNi/substrate, and annealing the leached PtNi/substrate nanoparticles, and forming a Pt-skin on the PtNi/substrate nanoparticles.
