Modification of Electrode Surfaces with Metallo Phthalocyanine Nanomaterial Hybrids
Abstract
The chapter reviews an electrocatalytic behavior of mononuclear metallophthalocyanines (MPcs) when combined with various nanomaterials. In addition, the chapter presents electrode modification using the least studied, binuclear phthalocyanines alone or in the presence of nanomaterials. The nanomaterials included are carbon nanotubes, metal nanoparticles, and semiconductor quantum dots. Different methods of electrode modification using MPc complexes in the presence of nanomaterials are presented. Methods of characterization of the modified electrodes, such as different types of microscopy, voltammetry, and X-ray photoelectron spectroscopy are presented. The chapter contains tables listing the reported electrode modification methods using MPcs in the presence on nanomaterials, and analytes detected on these electrodes. The chapter contains 149 references.
