抄録

We report the effects of straining and CO precover on H2 interaction with Pt determined by ab initio density functional calculations. Compressive (tensile) strain prevents (promotes) H2 dissociation and subsequent H adsorption. On the other hand, a CO neighbor prevents only H2 dissociation. Therefore, the catalytic activities for H2 dissociative adsorption are the best for realizing tensile-strained Pt, and the worst for realizing compressive-strained and CO-precovered Pt. We suggest that straining and/or CO precover can be used as a catalytic tailor for H2 dissociative adsorption.
