1 Molecular and Dissociative Adsorption of Oxygen on Au-Pd Bimetallic Clusters: Role of Composition and Spin State of the Cluster. Oxygen spindlin 1 Homo sapiens
2 Here, we present a systematic theoretical investigation of reaction pathways for O2 adsorption and dissociation on Au8, Pd8, and Au8-n Pd n (n = 1-7) nanoclusters in different spin states. Oxygen spindlin 1 Homo sapiens
3 The density functional calculations point out that the O2 dissociation barriers can be significantly reduced with the help of certain bimetallic clusters along specific spin channels. Oxygen spindlin 1 Homo sapiens
4 The enhanced O2 binding subsequently leads to low activation barriers of 0.98 and 1.19 eV along the doublet and quartet spin channels, respectively, without the involvement of any spin flip-over for O2 dissociation. Oxygen spindlin 1 Homo sapiens
