Comparing electrocatalytic and chemical oxygen reduction reaction by a molecular copper complex
Inspired by the Cu<sub>B</sub> site in C<i>c</i>O, a molecular Cu<sup>II</sup> complex (1) featuring a mixed pyridine-phenol ligand has been designed and synthesized. Electrocatalytic and chemical oxygen reduction reactions in the presence of 1 demonstrate a 4e<sup>-</sup>/4H<sup>+</sup> reduction of O<sub>2</sub>. Kinetic analysis reveals distinct reaction mechanisms for the chemical and electrocatalytic pathways and highlights the crucial role of the ligand backbone in the ORR process.
