Voltammetric, spectroelectrochemical, and electrocatalytic properties of thiol-derivatized phthalocyanines

摘要: Voltammetric and spectroelectrochemical properties electrocatalytic activities of thiol-derivatized phthalocyanine complexes for hydrogen production have been investigated. measurements show that while cobalt (CoPc) present well defined metal-based ring-based redox processes, all other give only reduction oxidation processes. The processes are generally diffusion-controlled, reversible one-electron transferred bearing tetra(acetoxyethylthio) substituents represents aggregation tendency in DCM solution. Cobalt nickel phthalocyanines easily electrodeposited on the GCE working electrode during repeating cycles positive potentials. Electrocatalytic indicated CoPc catalyzed proton via electro-reduced [CoIPc2−]1− and/or [CoIPc3−]2− species depending pH aqueous
