Hello group,
This got posted today on ecatnews.com [1]. It's a patent by Celani et
al. describing a process for the preparation of nanostructured layers on
nickel surfaces in order to achieve high hydrogen adsorption values at a
relatively low cost.

(shortened very long URL to the uspto.gov website)
Abstract: Thin nano structured layers on surfaces of nickel or its alloys for
quickly achieving high hydrogen adsorption values (H/Ni.about.0.7) through
direct metal/gas contact. The said layers are produced by a process comprising
the step of oxidising the said surfaces, applying a film of aqueous silica sol
to them, subsequent heating in an -oxidising atmosphere and final activation
through reduction in a reducing atmosphere.
Celani currently uses Romanowsky alloys (Cu-Ni) rather than pure nickel.
Also, from what I understand from his recent presentations, it appears
he improved the preparation process as of late.
The above linked patent has been filed two years ago (although approved
on May 31, 2012) and therefore might not be the state of the art
anymore. It still is an interesting and potentially informative read,
however.
Cheers,
S.A.
