Since the discovery of the ORR activity of cobalt phthalocyanine in 1964 [4], numerous studies have focused on the synthesis of non-precious metal ORR catalysts such as those based on carbon [5].

When deposited on surfaces, their interaction may be driven by dipolar forces mainly related to the organic cage and by a stronger interaction that is associated with the central metal atom. As an example, the adhesion of iron phthalocyanine (FePc) and cobalt phthalocyanine
