A DFT Study of the Adhesion of Pd Clusters on ZnO SWNTs and Adsorption of Gas Molecules on Pd/ZnO SWNTs
We investigated the adhesion of Pd nanoclusters on ZnO SWNTs and adsorption of probe gas molecules (O2, H2, and CO) on the outside or inside wall of ZnO and Pd1/ZnO SWNTs by means of density functional theory calculations in this study. Our study shows that the binding of Pd clusters on ZnO is mainly via the Pd-O bond interaction. The Pd monomer has the same adhesion ability on both the outside and the inside wall of ZnO SWNTs. However, we found that the adsorption energy of O2 is larger on the inside wall of ZnO and Pdi/ZnO SWNTs than that on the outside one, which is caused by the confinement effect.
