Advanced Polyphthalocyanine–Derived Electrode Materials for Energy Storage and Conversion

Abstract

Metal phthalocyanine, as one of the important synthetic metal-organic compounds, is similar with the natural metal porphyrins. Thanks to its unique structure and properties, phthalocyanines are constantly refurbished and excavated from blue dyes to third-order nonlinear optical materials, supramolecular self-assemblies, photoelectric-conversion materials, and liquid crystal materials. Since the cobalt phthalocyanine has been found with the electrocatalytic activity for oxygen reduction in 1964, the extensive researches on phthalocyanine-based compounds have been carried out in electrocatalysis and beyond. As the cross-linked products of phthalocyanines, polyphthalocyanines have a unique conjugated layered morphology with the various metal-N coordinated structure, demonstrating as the rational and facile materials and/ or precursors to construct the efficient electrode for energy conversion and storage device. In this work, we will present some of our rational and scalable strategies for developing the multi-variate and multi-scale materials from polyphthalocyanine for various renewable energy applications, including fuel cells, metal-air batteries, water splitting and supercapacitors. We anticipate that our strategies and electrode materials will also be useful for other electrochemical applications.
