TL;DR: It is demonstrated that alloying the Pd(110) surface with submonolayer amounts of Au dramatically accelerates the hydrogen absorption, thereby improving the performance of hydrogen-purifying membranes and hydrogen-storage materials, which is a key for utilizing hydrogen as a carbon-free energy carrier.

TL;DR: This small energy barrier suggests that the rate-determining step of the absorption process is either H2 dissociation on the H-saturated Pd surface or a concerted penetration mechanism, where excess H atoms weakly bound to energetically less favorable adsorption sites stabilize themselves in the chemisorption wells while pre-chemisorbed H atoms simultaneously transit into the subsurface.

TL;DR: In this article, the authors visualized the H distribution near a Pd single crystal surface charged with absorbed hydrogen during a typical catalytic conversion of butene (C4H8) to butane (C 4H10), using H depth profiling via nuclear reaction analysis.

TL;DR: Hydrogen quantitation and correct depth analysis require knowledge of the elementary composition (besides hydrogen) and mass density of the target material and (1)H((15)N,αγ)(12)C NRA is ideally suited for hydrogen analysis at atomically controlled surfaces and nanostructured interfaces.

TL;DR: In this article, the authors investigated coadsorption systems of H and CO on Habs-charged Pd(110) surfaces through temperature-programmed desorption, low-energy electron diffraction, and H-depth profiling by nuclear reaction analysis (NRA).
