“…[1][2][3] One of the most important properties of CMEs, in comparison to unmodified electrodes, is their ability to catalyze the electrode process with significant decrease of the needed overpotential. Metal complexes are well recognized for their excellent electrocatalytic properties toward the detection of hydrogen peroxide, [4][5][6] nitrite, 4-7 bromate 5-7 and trichloroacetic acid, 8 among other analytes. The wide range of electrochemical applications of metal complexes as, e.g, electrocatalysts for development of novel sensors and ion-carriers in ion-selective electrodes, has been reviewed.…”

(2), were synthesized and characterized by single crystal X-ray diffractometry, IR spectroscopy and elemental analysis. They were used as bulk modifiers for the fabrication of two carbon paste electrodes (Cu-CPE): 1-CPE and 2-CPE. They had similar electrochemical behaviors characterized by cyclic voltammetry and good electrocatalytic activities toward the reduction of hydrogen peroxide and trichloroacetic acid. The detection limits, linear calibration ranges and sensitivities were respectively 0.01 μmol L

Abstract:The present work reports the synthesis, characterization and performance of a new zinc(II) complex of [Zn(C 3 H 7 -bim) 2 Br 2 ] (bim = benzimidazole) as electrocatalyst for trichloroacetic acid and bromate reduction. Its structure was characterized by X-ray crystallography, IR spectroscopy and elemental analysis. The zinc atom adopts a distorted tetrahedral geometry by coordinating to two bromine atoms and two nitrogen atoms from two 1-propyl-1H-benzo[d]imidazole ligands. The electrochemical behavior and electrocatalysis of the zinc complex bulk-modified carbon paste electrode (Zn-CPE) have been studied by cyclic voltammetry. The Zn-CPE shows good electrocatalytic activities toward the reduction of trichloroacetic acid and bromate. The detection limit and the sensitivity are 0.05 μM, 67.43 μA μM -1 for trichloroacetic acid detection, and 0.02 μM, 69.94 μA μM -1 for bromate detection, respectively. This modified electrode shows good reproducibility, high stability, low detection limit, technical simplicity and possibility of rapid preparation, which is important for practical applications.

A functional composite of single-walled carbon nanotubes (SWNTs) with hematin, a water-insoluble porphyrin, was first prepared in 1-butyl-3-methylimidazolium hexafluorophosphate ([BMIM][PF(6)]) ionic liquid. The novel composite in ionic liquid was characterized by scanning electron microscopy, ultraviolet absorption spectroscopy, and electrochemical impedance spectroscopy, and showed a pair of direct redox peaks of the Fe(III)/Fe(II) couple. The composite-[BMIM][PF(6)]-modified glassy carbon electrode showed excellent electrocatalytic activity toward the reduction of trichloroacetic acid (TCA) in neutral media due to the synergic effect among SWNTs, [BMIM][PF(6)], and porphyrin, which led to a highly sensitive and stable amperometric biosensor for TCA with a linear range from 9.0x10(-7) to 1.4x10(-4) M. The detection limit was 3.8x10(-7) M at a signal-to-noise ratio of 3. The TCA biosensor had good analytical performance, such as rapid response, good reproducibility, and acceptable accuracy, and could be successfully used for the detection of residual TCA in polluted water. The functional composite in ionic liquid provides a facile way to not only obtain the direct electrochemistry of water-insoluble porphyrin, but also construct novel biosensors for monitoring analytes in real environmental samples.
