Electrocatalytic behavior of 4-(4,6-diaminopyrimidin-2-ylthio) phthalocyaninato cobalt(II) (CoPyPc) when mixed or covalently mixed to multiwalled carbon nanotubes (MWCNTs) is reported. Infra-red spectroscopy was used to confirm amide linkage of the covalently linked nanocomposite. Rotating disk electrode (RDE) and cyclic (CV) voltammetry studies were used for the electrochemical characterization of the prepared phthalocyanine and MWCNT nanocomposite. The electrocatalytic effects of the nanocomposites of the cobalt phthalocyanine derivative were then investigated towards l-cysteine oxidation using both RDE and CV experiments, and the electrocatalytic performance of the covalently linked cobalt phthalocyanine-MWCNT was found to be superior over the mixed nanocomposite.
A nanocomposite of 4-(4,6-diaminopyrimidin-2-ylthio) phthalocyaninato cobalt(II) with multiwalled carbon nanotubes (MWCNTs) showed good electrocatalytic activity towards l-cysteine oxidation when the two are covalently linked as opposed to when mixed without a chemical bond.Figure optionsDownload as PowerPoint slide
