Conductive carbon materials, such as graphite, glassy carbon, carbon black, carbon nanotube, graphene, etc., are used extensively as electrode materials or catalyst carriers in various electrochemical researches because it is inert in the electrode/electrolyte environment. It is well known that the under potential deposition (UPD) of hydrogen adatoms has never been observed on carbon materials.
We proposed, designed and demonstrated a “spillover-surface diffusion-chemical adsorption” system, and realized the stable chemisorption of atomic hydrogen on graphene by using platinum as catalyst and proton or water as hydrogen source. The experimental results of Raman spectroscopy evidenced the existence of C-H adsorption bond.
The kinetics of surface diffusion of hydrogen adatoms on graphene were also measured. This phenomenon is valuable for the hydrogen energy.
And here I always thought that Graphene is a zero-gap semiconductor, because its conduction and valence bands meet at the Dirac points. The Dirac points are six locations in momentum space, on the edge of the Brillouin zone, divided into two non-equivalent sets of three points. The two sets are labeled K and K’. The sets give graphene a valley degeneracy of gv = 2. By contrast, for traditional semiconductors the primary point of interest is generally Γ, where momentum is zero. Go figure.
But Carbon itself is considered a very high bandgap semiconductor. Perhaps when you whittle down Carbon to single-atom width, it goes from high bandgap to lowbandgap semiconductor.
Beyond that, four electronic properties separate it from other condensed matter systems.
Since you have the materials background, I’d suggest you look into Josephson Junctions and then Safire LENR junctions https://freerepublic.com/focus/chat/4008346/posts?page=16#16

Nobel prizes ain’t what they used to be since Jug Ears got one. And as well, all goes differently in a lab than commercially. Seemingly, it will always take more power to make power except for a few milliseconds in a lab.
That was the "Peace" prize, whose winners have mostly been flakes. The science prizes are still pretty legit.
