Gold in CO oxidation and PROX: The role of reaction exothermicity and nanometer-scale particle size

- Publications on CO oxidation over supported gold catalysts are subjected to a critical examination.
- Exothermicity is the cause of the reaction external diffusion control regime.
- Size distribution of gold metal particles is of the lognormal type.
- For samples synthesized under the same conditions, catalytic activity shows a uniform dependence on gold content.
