H Absorption into Metals

The effects of arsenic or sulphur-containing species
on H permeation into Fe or mild-steel have attracted
great interest. The absorption and permeation of H
into transition metals is commonly enhanced by
adsorbed catalyst poisons, which decrease the
coverage by adsorbed H, the intermediate in the
hydrogen evolution reaction. This unexpected
direction of behaviour has remained inadequately
explained.
The H/Pd system has also attracted major interest
because of its use as a permselective membrane for
the generation of ultra-high purity hydrogen and as
a model for interpretation of processes of H
sorption into metals. Therefore the effects of
chemisorption of arsenic or sulphur-containing
species on H transfer into and through Fe, mild-
steel, and comparatively, into Pd in aqueous NaOH
solution, and its relation to the hydrogen coverage
on the metal surface, has been extensively discussed
here from a kinetic point of view. This book will be
an invaluable reference for engineers and
professionals involved in the hydrogen production,
storage and embrittlement fields as well as the fuel
cell industry.

The effects of arsenic or sulphur-containing species on H permeation into Fe or mild-steel have attracted great interest.

This unexpected direction of behaviour has remained inadequately explained. The H/Pd system has also attracted major interest because of its use as a permselective membrane for the generation of ultra-high purity hydrogen and as a model for interpretation of processes of H sorption into metals. Therefore the effects of chemisorption of arsenic or sulphur-containing species on H transfer into and through Fe, mild-steel, and comparatively, into Pd in aqueous NaOH solution, and its relation to the hydrogen coverage on the metal surface, has been extensively discussed here from a kinetic point of view.
