| description |
The competitive adsorption of organic molecules (2,7-naphthalenedisulfonic
acid) and adsorbed His of interest in relation to its influence on H absorption
into a Pd-Ni electrodeposited alloy. The experimental results, in acid
solution, show an enhancement of the coverage of the electrode surface with
adsorbed H due to the competitive adsorption of organic molecules that
interfere with H atoms, through lateral attractive interactions between the
adsorbed species and communal electronic effects, leading supposedly to a
decreased probability of H entry into the alloy. Chemisorbed H is, on the
other hand, an intermediate in the HER, so the enhancement of the electrode
coverage in the presence of co-adsorbed organic molecules promotes the
hydrogen evolution reaction. |
