Platinum Nanoparticles in Energy Catalysts

What this topic covers

Why nanoscale dispersion exposes more active surface per unit mass.

Core energy-system ideas

Small particles provide a high fraction of atoms at or near the surface.

Particle size and shape influence catalytic activity and stability.

Nanoparticles can grow, dissolve or redistribute during long-term electrochemical service.

Important tradeoffs

Catalyst-layer performance emerges from reaction kinetics and transport at the same time.

Material and performance evidence

Lower platinum loading can increase sensitivity to local transport or degradation effects.

Lifecycle perspective

Manufacturing scrap is part of platinum material accounting and can be an important recycling stream.
