H2 Dissociative Adsorption on Strained/CO-Precovered Pt

概要
- 論文の詳細を見る
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.
