Electroreduction of Nitrobenzene on Palladium Implanted Glassy Carbon Electrodes in Acidic Solution
Abstract:
The electroreduction process of nitrobenzene (NB) in 0.5 mol/L sulfuric acid solution was studied by cyclic voltammetry by using palladium implanted glassy carbon(GC) eletrodes.The surface composition of implanted electrode and concentration depth profiles of various elements were measured by AES. Implantation of palladium into GC at 40 keV to a fluence of 1×1017 ions·cm-2 produced a surface-near region with a maximum atomic concentration of 20% palladium.The implanted substrates are much more active than the untreated ones in the electroreduction of NB. Aniline was detected as a reduction product of NB by using gas chromatographic methods. The electroreduction mechanism of NB in acidic solution is discussed.
