Potentiostatic switching experiments for the cathodic reduction of nitrous acid in perchloric acid with the addition of nitric acid

In Situ Attenuated Total Reflection Infrared (ATR-IR) Study of the Adsorption of NO2-, NH2OH, and NH4+ on Pd/Al2O3 and Pt/Al2O3

“…In electrochemical research, electrocatalytic reaction of inorganic nitrogen compounds on transition metals is a classical topic. The electrochemical reduction of nitrate was shown to be more complex than the catalytic hydrogenation shown in Scheme . , Electrochemical reduction has been mainly investigated on platinum electrodes, and this has indicated the presence of a variety of intermediates such as NO 2 , HNO 2 , NO, N 2 O, N 2 , H 2 NO, HNO, NH 2 OH, and NH 3 , depending on reaction conditions. − Similar to the heterogeneous catalytic reaction, the rate-determining step is the reduction of nitrate to nitrite, which in turn yields adsorbed NO. − Several papers report on the experimental evidence of adsorbed NO as an intermediate during electroreduction of nitrate and nitrite. ,− The subsequent electroreduction of adsorbed NO mainly yielded ammonia, while traces of N 2 O were also detected. In addition, N 2 O was demonstrated to be an intermediate for the production of nitrogen from nitrate on platinum electrodes. , …”

Creation of Nanoporous Ag Surface Layers through a Two-Stage Electrochemical Deposition-Dissolution of Zn and Intercalation-Deintercalation of Chloride Ions in an Ionic Liquid Bath

“…Literature results indicate that the limiting-currents are controlled by a preceding chemical reaction rather than mass transport and can be increased by increasing electrode surface area. 44,45 The nanoporous networks of Ag surface are likely to facilitate the preceding chemical reaction.…”
