Structure sensitivity in adsorption: CO interaction with stepped and reconstructed Pt surfaces Structure sensitivity in adsorption: CO interaction with stepped and reconstructed Pt surfaces ============================================================================================== by B. Hammer, O. H. Nielsen, and J. K. Nørskov. Catalysis Letters, **46**, 31 (1997). Abstract -------- The structure sensitivity of CO adsorption on different flat, stepped, kinked and reconstructed Pt surfaces is studied using large scale density-functional calculations. We find an extremely strong structure sensitivity in the adsorption energy with variations up to 1 eV (or 100\\%) from one structure to the next. We propose a model to explain this behavior, and use it to discuss more generally the origin of structure sensitivity in heterogeneous catalysis.
