Nitride Stabilized PtNi Core–Shell Nanocatalyst for high Oxygen Reduction Activity

We describe a route to the development of novel PtNiN core–shell catalysts with low Pt content shell and inexpensive NiN core having high activity and stability for the oxygen reduction reaction (ORR). The PtNiN synthesis involves nitriding Ni nanoparticles and simultaneously encapsulating it by 2–4...
