Paper Title:
Carbon Nanotubes-Doped Glassy Carbon Ceramic Composite Electrode and its Electrocatalytic Reduction of Nitrite
  Abstract

A conductive glassy carbon ceramic composite electrode (GCCE) comprised of multi-walled carbon nanotubes (MWNTs) and glassy carbon microparticles in an organically modified silicate matrix was fabricated using a sol-gel method. The electrode thus prepared exhibits electrocatalytic behavior to the reduction of nitrite and facilitates the detection of nitrite at an applied potential of 0.0 V. A linear range from 2.5×10-5 to 3×10-3 M for the detection of sodium nitrite has been observed at the composite electrode with a sensitivity of 9.6 μA/mM and a detection limit of 9×10-6 M based on a signal-to-noise ratio of 3.
