Adsorption/absorption/reaction of hydrogen and deuterium on/in palladium (H/D-Pd) are important in both fundamental research and application, especially for hydrogen energy and other unexplored energies. The behaviour of H/D in subsurface of Pd metal is distinctively different from that at the surface and in the bulk phase.

It could be possible to have overloading of H/D in the subsurface and create some unique lattices and configurations with input energy pulse. It’s therefore highly desirable to comprehensively understand the H/DPd subsurface systems on many aspects.

However, it’s not easy to isolate the subsurface experimentally and avoid large discrepancies between the experiment and theoretical calculation. Recently, we have tried to systematically study H/D-Pd monolayer(s) coated on structurally well-defined Au single-crystal electrodes and nanoparticles.

Two methods, i.e., indirectly redox replacement of Cu UPD layer and directly electrochemical deposition of Pd, were developed to well control the Pd atomistic layer from 1 to 3, 5 monolayers over Au(111), (100) and (110) facets and Au nanoparticles of ~ 50 nm in diameter, respectively. The Pd layer, crystal facet, applied potential and electrolyte dependences were studied using cyclic voltammetry and in-situ Raman spectroscopy.

The metal surfaces and subsurface of various monolayers were modelled with the first-principles computations using the Vienna ab initio simulation package (VASP), which will be discussed in detail.

If someone says stop, then stop. Do not enter onto a thread on a topic you don’t like just to disrupt, rattle cages, poke sticks, insult the regulars, or engage in trolling activities, etc. ~Jim Robinson

The issue isn’t whether we allow skepticism, it is whether we allow hyperskeptics and skeptopaths to ruin the scientific dialog. Such FReepers who persist in polluting these threads have been asked to leave, and we are asking that they open their own threads if they have comments.

This topic has a following, people who wish to learn and discuss the materials presented.

Please refrain from posting anything that doesn’t legitimately address the issue.

Something is going on in this segment of science. There are a considerable number of research groups studying the matter.

I would really like to see one of these system become a commercially viable energy source.

I'm pretty good with numbers.

I'm lost on this stuff.

I do wonder why they are trying to use gold as a sub surface instead of ceramic or silicon to avoid any potential interference between the Palladium and any other metal, gold in this case. I’m sure there was a reason, but the key may be having two types of material that behave differently instead of similarly. i’m sure, I like the lightbulb, there are all sorts of materials being used and tested.

Sorry about the typos. I am trying to do this on my phone.

Au nanoparticles and monofilms/monolayers have characteristic properties that no other nanometals possess. I work with Au nanoparticles. Their behaviors are barely understood; thus much experimentation is ongoing as many little surprises pop up every day.

How good are they for absorbing hydrogen?

Do you know the Freeper Marshmallow? You 2 should team up to make the world’s most confusing physics/catholic post title ever conceived that will make anybody’s head explode just reading it. (joking)

Yes yes. But how is it racist?
