“…In this paper, it is shown that the introduction of 10% of rhodium in the electrode composition changes the reactivity of the electrode for the electrochemical reduction of nitrite ions. The reaction onset is delayed and there is simultaneous production of NO and N 2 O, contrasting with pure platinum [7], where NO and N 2 O are produced at different electrode potentials.…”

“…But a number of studies provide a working hypothesis. Nishimura et al (1991) found that nitrate ions were reduced to the desired product nitrogen gas via several intermediate products involving NO 2 À , NO, N 2 O, and at the same time, OH À and ammonium ions were produced. Products produced by the electrolysis depend on the electrode materials.…”

“…Bien qu'il soit bien connu que l'oxydation de l'éthanol sur des electrodes en platine suive des processus réactionnels parallèles menant à l'acétaldéhyde, à l'acide acétique et au CO 2 , le mécanisme de cette réaction reste peu clair. Les études précédentes basées sur des techniques spectroscopiques linéaires ont contribué sensiblement à la compréhension de l'oxydation de l'éthanol sur le platine.…”

“…Notoriamente, a eletro-oxidação de etanol sobre platina ocorre por diferentes caminhos paralelos de reação que conduzem à formação de acetaldeído, ácido acético e CO 2 . No entanto, o mecanismo desta reação permanece incerto.…”
