Hydroxylamine electrochemistry at polycrystalline platinum in acidic media: a voltammetric, DEMS and FTIR study

Role of germanium in promoting the electrocatalytic reduction of nitrate on platinum: An FTIR and DEMS study

“…9c, solid line). Similar trends in the formation of both nitric oxide and nitrous oxide were observed for the oxidation of hydroxylamine at polycrystalline platinum [39], suggesting that, besides ammonia, hydroxylamine is indeed a reduction product of nitrate at platinum in the presence of germanium. Another significant observation is the formation of some gaseous NO simultaneously with the nitrate reduction current (below 0.2 V).…”

New insights into the mechanism of nitrite reduction on a platinum electrode

“…At higher pH values HAM is even more oxidizable and there is no longer a loop but the current for HAM oxidation is higher in the negative-going scan within a much wider potential window. Detailed analysis of this voltammetric feature was reported by Rosca et al [34] where it was ascribed to enhanced HAM oxidation during the negative-going scan due to higher reactivity of the platinum surface following oxidative removal of NO ad in the previous positive-going sweep.

On-line mass spectrometry system for measurements at single-crystal electrodes in hanging meniscus configuration

“…As a final example, we recently studied in some detail the electrochemistry of hydroxylamine (HAM) at polycrystalline platinum [21] and single-crystalline platinum [22]. One of the oxidation products found was nitrous oxide N 2 O.…”
