An isotopic labeling investigation of the mechanism of the electrooxidation of hydrazine at platinum

Electrocatalytic oxidation of hydrazine on platinum electrodes in alkaline solutions

“…The electrooxidation of hydrazine on polycrystalline platinum has been the subject of several detailed mechanistic studies in both acidic and alkaline solutions [1][2][3][4][5][6][7][8][9]. On-line electrochemical mass spectrometry (MS) measurements confirmed that reaction proceeds predominantly at the N H bond and that molecular nitrogen is the dominant product [7].…”

“…On-line electrochemical mass spectrometry (MS) measurements confirmed that reaction proceeds predominantly at the N H bond and that molecular nitrogen is the dominant product [7]. The reaction is commonly viewed as a step-wise electrochemical dehydrogenation process [10].…”

Application of a Palladium Hexacyanoferrate Film-Modified Aluminum Electrode to Electrocatalytic Oxidation of Hydrazine

“…The mechanism and kinetics of hydrazine oxidation have been studied at several electrodes, including silver, 4 nickel, 5 gold 4 mercury 4,6,7 and platinum. [7][8][9][10] Unfortunately, the electrode process of hydrazine at conventional electrodes involved a large anodic overpotential, thus it is not a suitable analyte for these electrodes. One promising approach for minimizing overpotential effects is the use of an electrocatalytic process at chemically modified electrodes.…”

On-line electrochemistry – MS and related techniques

“…Bruckenstein and co-workers [2,3,4,5] and later mainly Heitbaum et al used this technique extensively to identify volatile reaction products [6,7,8,9,10,11,12,13,14,15,16,17,18]. Similar techniques were employed in the nineteen-eighties and later by Kreysa and Breidenbach [19], Anderson and co-workers [20,21,22], and Iwasita and co-workers [23,24].…”
