Carbon Monoxide Promotes the Catalytic Hydrogenation on Metal Cluster Catalysts
Adsorption energy of H2 on Pd with different sizes. Calculated on bare (marked in black circle) and TiO2(010)-supported (marked in red triangle) clusters. The hollow and solid symbols are denoted as the CO-free and CO-modified cases, respectively. The gray dashed lines represent on Pd(111) and Pd(100). The blue, dark gray, red, and white balls represent Pd, C, O, and H atoms. The size of Pd clusters was estimated by .
