“…Various studies have focussed on the electrochemical oxidation of ammonia in alkaline solutions, 39 and as a result, several protocols based on its determination via its direct oxidation have been developed. Mechanistic studies for the oxidation of ammonia have been reported in the aprotic solvents acetonitrile (MeCN), 40 dimethyl formamide (DMF), 41 propylene carbonate (PC), 42 Figure 8 shows the oxidation of ammonia (10% NH 3 , 90% N 2 ) on a Pt microdisk electrode (diameter = 10 m) in the RTIL [C 4 mim][BF 4 ] at a scan rate of 10 V s -1 . Peak I corresponds to the direct oxidation of ammonia, and peaks II, III and IV have been shown 18 to be due to the following electro-generated products; the solvated proton (H[BF 4 ] x ), ammonium ion (NH 4 + ) and adsorbed hydrogen (H 2 ) respectively.…”

A eletroquímica de compostos inorgânicos simples em líquidos iônicos a temperatura ambiente (RTIL) é revisada e alguns trabalhos novos nesta área são apresentados. Este artigo focaliza a comparação entre o comportamento eletroquímico em RTILs e em solventes apróticos convencionais. Alguns compostos (iodetos, O 2 , NO 2 , SO 2 , NH 3 ) apresentam reações e mecanismos similares em RTILs e em solventes apróticos (como é observado para compostos orgânicos). Entretanto, outras espécies (nitratos, PCl 3 , POCl 3 ) mostram comportamento excepcionalmente diferente em relação aos solventes tradicionais. Isto torna os RTILs um meio promissor para o estudo de compostos inorgânicos, e destaca a necessidade de maiores investigações nesta área.The electrochemistry of simple inorganic compounds in room temperature ionic liquids (RTILs) is reviewed and some new work in this area is presented. This paper focuses on the comparison between electrochemical behaviour in RTILs and in conventional aprotic solvents. Some compounds (iodides, O 2 , NO 2 , SO 2 , NH 3 ) display similar reactions and mechanisms in RTILs as in aprotic solvents (as is observed for organic compounds). However other species (nitrates, PCl 3 , POCl 3 ) show remarkably different behaviour to traditional solvents. This makes RTILs very promising media for the study of inorganic compounds, and highlights the need for more investigations in this exciting area.

“…This conclusion has been confirmed by results obtained by Huerta et al [10,11] on monocrystalline Pt electrodes. A dual mechanism depending on the electrode potential has been proposed by Mann et al [12,13] for the oxidation of aliphatic amines in acetonitrilic solution. Studies on gold have been limited only to the anodic oxidation of ethylamine in aqueous alkaline media.…”

The kinetics of methylamine oxidation at a gold electrode in contact with an alkaline electrolyte solution was studied. The adsorptive behaviour of substrate molecules was determined by changes in the differential capacitance of the double layer at the electrode/solution interface. The electrooxidation of methylamine occurs only in the potential range of gold oxide layer formation. The general reaction pathways of methylamine oxidation on the gold electrode is proposed.

“…In spite of the unquestionable significance of aliphatic amines in industrial, clinical and environmental applications [30] their electrochemical behaviour has been scarcely examined. For platinum electrodes in acetonitrile, Mann et al [31,32] have established that the mechanism of oxidation of aliphatic amines depends on the electrode potential. Hora´nyi et al [33,34] have postulated that the oxidation of methylamine and butylamine at a platinized platinum electrode in acidic, as well as in alkaline medium, leads to adsorbed cyanide species.…”

The electrooxidation of isomeric butylamines at a gold electrode in contact with an alkaline electrolyte solution was studied by cyclic voltammetry. Differences in the electrochemical activity of the isomers were found. It was ascertained that the amine oxidation is catalysed by the gold oxide layer. Substrate molecules are adsorbed on the gold electrode surface in the potential range preceding the oxidation. The adsorptive behaviour of the substrate molecules was evaluated on the basis of changes in the differential capacitance of the double layer at the electrode/solution interface.
