Interaction of Hydrogen with Au Modified by Pd and Rh in View of Electrochemical Applications

Hydrogen interaction with bimetallic Au(Pd) and Au(Rh) systems are studied with the density functional theory (DFT)-based periodic approach. Several bimetallic configurations with varying concentrations of Pd and Rh atoms in the under layer of a gold surface(111) were considered. The reactivity of the doped Au(111) toward hydrogen adsorption and absorption was related to the property modificati...

Hydrogen sensing by localized surface plasmon resonance in colloidal solutions of Au-WO3-Pd

Nowadays, hydrogen has attracted significant attention as a next generation clean energy source. Hydrogen is highly flammable, so detection of hydrogen gas is required. Gold nanoparticle based localized surface plasmon resonance (LSPR) is an advanced and powerful sensing technique, which is well known for its high sensitivity to surrounding refractive index change in the local environment. We p...

Hydrogen Adsorption and Absorption with Pd−Au Bimetallic Surfaces

Pd−Au bimetallic catalysts have shown promising performance in numerous reactions that involve hydrogen. Fundamental studies of hydrogen interactions with Pd−Au surfaces could provide useful insights into the reaction mechanisms over Pd−Au catalysts, which may, in turn, guide future catalyst design. In this study, the interactions of hydrogen (i.e., adsorption, absorption, diffusion, and desorp...

Application of Pd-Substituted Ni-Al Layered Double Hydroxides for the Hydrogen Evolution Reaction

Clean production of hydrogen from electrochemical water splitting has been known as a green method of fuel production. In this work, electrocatalytic hydrogen evolution reaction (HER) was investigated at new prepared layered double hydroxides (LDH) in acidic solution. NiAl/carbon black (CB) LDH was monitored using x-ray diffraction (XRD), Fourier transform infrared (FT-IR) spectroscopy, scannin...

Hydrogen adsorption energies on bimetallic overlayer systems at the solid-vacuum and the solid-liquid interface

Atomic hydrogen adsorption energies on bimetallic overlayer systems have been determined by periodic density functional theory calculations within the generalized gradient approximation. On the pseudomorphic Pd/Cu(111) surface, both the substrate interaction and the lattice compression of the Pd overlayer lead to smaller hydrogen binding energies. For pseudomorphic Cu/Pd(111), on the hand, the ...
