In this paper we report on synthesis and electrocatalytic behavior of cobalt (II)-tris(benzyl-mercapto)monoaminophthalocyanine-single walled carbon nanotube nanorods towards the oxidation of amitrole. SWCNTs that were terminally functionalized with carboxylic acid groups were chemically linked to cobalt (II)-tris(benzyl-mercapto) monoaminophthalocyanine (CoMAPc) via an amide bond to form nanorods. UV-vis, FTIR, TEM, Raman and XRD spectroscopies were used in characterization of the nanorods (CoMAPc-SWCNT-linked), while cyclic voltammetry and chronoamperometry were used during the characterization of amitrole on the modified glassy carbon electrode. The linear dynamic range for the amitrole was from 1.0 x 10(-6) M to 1.2 x 10(-4) M, with a sensitivity of 6.76 A mol(-1) L cm(-2). The estimated limit of detection for amitrole was 0.10 mu m, using the 35 criterion. The catalytic rate constant was found to be 1.09 x 10(5) M-1 s(-1). (C) 2010 Elsevier Ltd. All rights reserved.
