4 shows electrochemical signatures similar to those of the homogeneous system. Its electrocatalytic water oxidation performance at pH 1 has been investigated by rotating ring disk electrode (RRDE) measurements, and high faradaic efficiency is evidenced by the agreement of Tafel slopes for the disk and ring currents. X-ray photoelectron spectroscopy (XPS) data before and after electrochemical measurements were compared to evaluate the chemical stability of the immobilized complex 4 during catalysis, showing that the surface-bound complex species remains intact without any decomposition to RuO2. However, gradual leaching of the complex leads to decreasing catalyst concentration and decreasing activity during electrocatalysis, reflecting weak attachment of the carboxylate anchor to the oxide substrate and emphasizing the need for improved anchoring strategies.
