AI Article Synopsis

  • Monomeric cobalt(II) tetraphenylporphyrin is immobilized in a polymer made from vapour-phase polymerized polypyrrole on an ITO electrode.
  • This setup acts as a catalyst for the reduction of dioxygen (O2) to water (H2O) through a process that involves four electrons.
  • The reaction necessitates the simultaneous involvement of two distinct catalytic groups to function effectively.

Article Abstract

Monomeric cobalt(II) tetraphenylporphyrin immobilized in high concentrations within vapour-phase polymerized polypyrrole deposited on an ITO electrode catalyzes the 4-electron reduction of dioxygen to water, a reaction requiring concerted action by two separate catalytic groups.
