It just occurred to me to check how the copper was plated on in the research engine:
"...using a standard electroplating process...using cyanide copper bath (Poola 1993), which produces a coating of
porous nature and a fine deposition of metal on the surface...thin coatings (about 20-60 microns)..."

Sounds to me like the porous nature means a higher surface area.
Why the "fine deposition" is also mentioned; I dont know.
Perhaps a fine deposition rather than a solid 'plate' of copper is less likely to come lose due to different coefficients of expansion.
The questions of durability and carbon fouling of the catalyst surface are not answered in the study.
However I NB that red hot carbon + Steam = H + CO as used in Syngas production.
ie: Steam, an end product of HC combustion in O2, is cleaning mechanism for your catalytic surface that just so happens to also produce H.
It's also very easy to add extra water mist or steam to the intake mix and its temporary addition is an old method of cleaning carbon out of engines.
