文摘
- •
Impact of structural ordering and gold doping on stability of PtCu3 was studied.
- •
Structurally ordered PtCu3 nanoparticles retain more Cu than the disordered ones.
- •
Doping PtCu3 nanoparticles with Au results in further inhibition of Cu dissolution.
- •
Doping PtCu3 nanoparticles with Au considerably inhibits dissolution of Pt.
- •
Particle size remains the dominant effect as regards the stability of catalysts.
