Exploring ligand-centered electrocatalytic H2O reduction: hydrogen generation with a soluble Ni(ii) octabutoxyphthalocyanine complex

Abstract

A nickel(II) octabutoxyphthalocyanine complex demonstrating ligand-centered redox activity and pH dependence is reported and investigated as an electrocatalyst for hydrogen evolution from water. Spectro- and electrochemical methods were implemented to further elucidate the nature of the pH dependence and catalytic mechanism.
