Insights into the electrocatalysis of nitrobenzene using chemically-modified carbon nanotube electrodes
The electrochemical behavior of nitrobenzene and its derivatives at chemically-functionalized multi-wall carbon nanotubes (MWNTs) modified electrodes was studied. Experimental results showed that hydroxyl-containing MWNTs exhibited the highest electrocatalytic activity among the used MWNTs because o...

Sumario: | The electrochemical behavior of nitrobenzene and its derivatives at chemically-functionalized multi-wall carbon nanotubes (MWNTs) modified electrodes was studied. Experimental results showed that hydroxyl-containing MWNTs exhibited the highest electrocatalytic activity among the used MWNTs because of its weak capacitive features and oxygen-containing functional groups. The cycle voltammetrys of nitrobenzene derivatives on the MWNTs modified electrodes can be easily tuned by changing the substituted groups of nitrobenzene. Based on the experimental data, the electrochemical reaction mechanisms of nitrobenzene and its derivatives on the MWNTs modified electrodes have been discussed and analyzed. |
