9, 10-Phenanthrenequinone (PQ) supported on glassy carbon microparticles by adsorption was dispersed in methyltrimethoxysilane (MTMOS) derived gels to yield a conductive composite which was used as electrode material to fabricate a PQ-modified glassy carbon ceramic composite electrode. It shows good electrocatalytic activity toward the reduction of iodate and could be used as an amperometric sensor for the determination of iodate in table warter.

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.
