Synthesis, characterization and the electrocatalytic behaviour of nickel (II) tetraamino-phthalocyanine chemically linked to single walled carbon nanotubes

In this work we report on the synthesis, characterization and the electrochemical behavior of amide linked nickel (II) tetraamino-phthalocyanine (NiTAPc)-single walled carbon nanotube (SWCNT) nanomaterials (NiTAPc-SWCNT (linked)). UV–vis, XRD, IR and Raman spectroscopies were used in characterizatio...

description In this work we report on the synthesis, characterization and the electrochemical behavior of amide linked nickel (II) tetraamino-phthalocyanine (NiTAPc)-single walled carbon nanotube (SWCNT) nanomaterials (NiTAPc-SWCNT (linked)). UV–vis, XRD, IR and Raman spectroscopies were used in characterization whilst cyclic voltammetry was used to study the electrochemical behavior of NiTAPc-SWCNT (linked)-GCE. Relative to the bare glassy carbon electrode (bare-GCE), SWCNT-GCE, NiTAPc-GCE, and NiTAPc/SWCNT (mixed)-GCE, the NiTAPc-SWCNT (linked)-GCE gave the best current responses for the oxidation of 2-mercaptoethanol (2-ME). The catalytic rate constant is of the magnitude of 103 M−1 s−1 while the detection limit (LOD) is 0.15 μM using the 3δ notation, with a sensitivity of 2.53 μA μM−1 cm−2.
