Catalytic oxidation of propane over palladium alloyed with gold: an assessment of the chemical and intermediate species

The surface intermediate species for catalytic oxidation of propane depend strongly on the catalyst composition.

Density Functional Study of Trimetallic AuxPdyPtz (x + y + z = 7) Clusters and Their Interactions with the O2 Molecule

Density functional theory calculations were performed to investigate the structural and energetic properties of trimetallic Au_xPd_yPt_z clusters with x + y + z = 7. The possible stable geometrical configurations with their electronic states are determined. We analyze the chemical order, binding energies, vertical ionization potential, electron affinity, and HOMO-LUMO gaps as a function of the whole concentration range. The affinity of Au_xPd_yPt_z clusters toward one O₂ molecule is also evaluated in terms of the changes in geometry, adsorption energy, and charge transfer.

Tailoring the structure and electronic properties of platinum and gold–platinum nanocatalysts towards enhanced O2 activation

The structural designing of a precious metal molecular catalyst by doping is proved to significantly enhance its activity.

Tuning metal cluster catalytic activity with morphology and composition: a DFT study of O2 dissociation at the global minimum of PtmPdn (m + n = 5) clusters

The catalytic property for O₂ dissociation of the pure Pt₅ cluster can be further improved by introducing the Pd atoms based on the morphology and composition.

The role of hydrogen during Pt–Ga nanocatalyst formation

The behavior and role of hydrogen is investigated by using Pt–Ga nano-alloy formation as a probe reaction.
