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.

Cobalt Phthalocyanines

Investigations of the electrocatalytic activity of mononuclear and binuclear cobalt phthalocyanines for the reduction of molecular oxygen established that the latter compounds are more effective catalysts than the corresponding mononuclear species. A correlation between the half-band widths for the Q band of these species and their catalytic efficiency, expressed as a kinetically-limited current, suggests that the increase in activity may be attributed to electronic coupling between the phthalocyanine rings.

Array Electrode

A Zr4+-doped anatase TiO2 nanotube array electrode was prepared using a process that included Ti anodizing, chemical immersion, and heat treatment. The compositions, microstructure, and electrochemical properties of the prepared electrodes were characterized. The results show that Zr4+ was successfully introduced into the TiO2 nanotube array electrodes. Because Zr4+ was doped into the crystal structure of the TiO2and replaced a part of Ti4+ to form more oxygen vacancies and Ti3+, the electrocatalytic activity of the prepared electrodes, for the reduction of L-cystine, was significantly improved.
