Atomic layer deposition in the preparation of Bi-metallic, platinum-based catalysts for fuel cell applications

- ALD is solvent-free, controlled method suitable for preparing bimetallic particles.
- Metal location and particle size effecting catalyst activity was modified by ALD.
- Synthetized nanoparticles have well defined surface structure.
- The catalysts show enhanced activity for important fuel cell reactions MOR and ORR.
- Catalyst durability in MOR is adjusted by suitable catalyst preparation parameters.
