Systematic study of transition-metal (Fe, Co, Ni, Cu) phthalocyanines as electrocatalysts for oxygen reduction and their evaluation by DFT

A facile approach is reported to prepare a series of transition-metal phthalocyanines supported on graphitized carbon black (TMPc/GCB, TM: Fe, Co, Ni and Cu) as oxygen reduction reaction electrocatalysts,viaπ–π interaction self-assembly.
