We investigate the structure sensitivity of the water-gas shift reaction on Pt, showing that the stepped surfaces Pt(322) and Pt(211) exhibit much higher activities than Pt(111). Statistical analysis of reaction occurrence elucidates the contribution of steps and terraces on the observed rates, indentifying the active sites for each elementary reaction.
