A microkinetic model for CO adsorption and dissociation on polycrystalline Fe developed from CO TPD data provides new mechanistic insights and kinetic parameters for modeling elementary steps as a function of coverage, adsorption temperature, promoter level, and metal dispersion. Adsorption and desorption processes increase in complexity with increasing metal dispersion.
