Processing of α-Phase Metal?Phthalocyanine Powders by Interface Neutralization Method

Abstract

Metal phthalocyanines (MPcs; M = Co, Ni, Cu, Zn) with α-phase powders were obtained at the interface between hydrophilic and hydrophobic solutions starting from β-phase powders. This method was also applied to the deposition of a highly dispersed α-phase MPc on a carbon substrate, which showed high electrochemical activity for oxygen reduction.
