abstract = {The structure sensitivity of the reduction of nitrate has
been studied on a series of single-crystal platinum
electrodes by cyclic voltammmetry and in situ FTIRAS in
sulfuric and perchloric acid solutions. The nitrate
reduction is a structure-sensitive reaction on
single-crystal platinum electrodes. However, this structure
sensitivity is essentially controlled by other species
(hydrogen, sulfate) that interact strongly with the
electrode surface rather than by a structure-sensitive
nitrate adsorption, dissociation or reduction.Voltammetric
and spectroscopic data point to adsorbed nitric oxide (NO)
as the main stable intermediate of the nitrate reduction to
ammonia. No evidence for the formation of N2O was found. On
surfaces with sufficiently wide (111) terraces in the
absence of specifically adsorbed sulfate, an oxidizable
nitrate reduction product is detected voltammetrically,
which may tentatively be attributed to the formation of a
small amount of hydroxylamine earlier during the
voltammetric scan. (C) 2005 Elsevier Ltd. All rights
