Nitride stabilized core/shell nanoparticles
Patent
·
OSTI ID:1651006
Nitride stabilized metal (M or Pt(M)) nanoparticles and methods for their manufacture are disclosed. In one embodiment the metal nanoparticles have a nonporous noble metal shell with a nitride-stabilized non-noble metal core. The nitride-stabilized core provides a stabilizing effect under high oxidizing conditions suppressing the noble metal dissolution during potential cycling. Introduction of nitrogen into the core by annealing produces metal nitride(s) that are less susceptible to dissolution during potential cycling under high oxidizing conditions.
