Density Functional Calculations of the Sequential Adsorption of Hydrogen on Single Atom and Small Clusters of Pd and Pt Supported on Au(111)

Autor: Joshua Melendez-Rivera, Juan A. Santana

We have used density functional theory calculations to study the sequential adsorption of hydrogen on Pd and Pt atomic site catalysts such as single atom alloy catalyst (SAAC), single atom catalyst (SAC), and single clusters catalyst (SCC) of on Au(1

Hydrogen Adsorption on Au-Supported Pt and Pd Nanoislands: A Computational Study of Hydrogen Coverage Effects

Autor: Joshua Melendez-Rivera, Juan A. Santana

Publikováno v: J Phys Chem C Nanomater Interfaces

We have studied the dissociative adsorption of hydrogen under high coverage conditions of adsorbed hydrogen on Pd and Pt nanoislands supported on Au(111) using Density Functional Theory calculations. The results reveal that for Pd/Au(111), the free e

Strain and Low-Coordination Effects on Monolayer Nanoislands of Pd and Pt on Au(111): A Comparative Analysis Based on Density Functional Results

Autor: Juan A. Santana, Bryan Cruz, Joshua Melendez-Rivera, Notker Rösch

Publikováno v: J Phys Chem C Nanomater Interfaces

Recent experiments demonstrated that the catalytic centers for the hydrogen evolution reaction (HER) are different on Pd and Pt nanoislands on Au(111). Inspired by these experiments, we examined the geometric, energetic, electronic and hydrogen adsor
