Title
Characterization and functional assessment of a cobalt(III)-oxo cubane cluster water oxidation catalyst immobilized on ITO
Abstract

•We used electrochemical deposition to anchor a water oxidation catalyst to ITO.•We applied a variety of characterizations before and after immobilization.•We also assessed catalyst function before and after immobilization on the substrate.•Results showed that immobilized catalyst functions in the same way as in solution.•Separation of synthesis and deposition has potential for rational optimization.

A cobalt(III) oxo cubane water oxidation catalyst, a structural mimic of the natural oxygen-evolving center, was immobilized on indium tin oxide (ITO) to promote recycling. The structure and composition of the complex were characterized by Fourier transform-infrared (FT-IR) spectroscopy, surface FT-IR, scanning electron microscopy, and energy dispersive X-ray spectroscopy. Cyclic voltammetry was used to assess catalyst functionality, stability, and recyclability. The results showed that this catalyst can be successfully immobilized on ITO, and that the complex functions in the same manner as the free catalyst in solution. This separation of synthesis and immobilization has great potential for optimizing heterogeneous catalysts.
