Influence of the molecular structure of metal-phthalocyanine on electrocatalytic reactions

Abstract

The demand for new catalysts for renewable energy production has become crucial. As an alternative to metal catalysts for electrocatalysis to produce energy sources, metal-phthalocyanine (MPc) electrocatalysts have shown potential. Their physicochemical and electrochemical properties depend on the chemical structure of the MPc and the central metal atom. Recent reviews of MPcs focused on their electrochemical performance in specific catalytic reactions, such as oxygen reduction reaction and CO2 reduction reaction. However, understanding the structure of MPcs in depth is important, since their electrochemical catalytic activity is affected by structural modifications of MPcs. Therefore, this minireview focuses on how the molecular structure of MPcs affects electrochemical catalysis.
