Modifications produced by O plasma treatments on a 2 mesoporous glassy carbon * ́ ́ ́ ́
نویسنده
چکیده
A glassy carbon, P3, obtained by carbonization of polyfurfuryl alcohol was used to study the changes produced by oxygen plasma treatments which were compared to those obtained by molecular oxygen. The sample was selected for its well defined mesoporosity. The aim was to study the influence of porosity on the reactivity of the sample in oxygen plasma. The results were compared to previously reported data obtained using a glassy carbon with no macro or mesoporosity. It is concluded that the influence of mesoporosity is almost negligible in such a way that only the external surface was affected by plasma treatment. 2000 Elsevier Science Ltd. All rights reserved.

A sensor, based on multi-wall carbon nanotubes modified glassy carbon electrode (MWCNT/GCE), was developed for determination of fenitrothion. Determining the surface area of MWCNT/GCE showed that this surface is three times more active than that of a glassy carbon electrode. The experimental parameters, such as the amount of MWCNTs, pH of the fenitrothion solution, preconcentration potential an...
