Materials composed of immobilized water oxidation catalysts on metal oxide supports have recently become a significant target in the field of solar fuels, for their use in the production of devices. These materials utilize electrostatic and atomic-layer deposition (ALD) protection techniques to bind POM WOCs and the light-absorbing supports (TiO₂, BiVO₄, and CdS quantum dots) for photoelectrochemical water oxidation systems.

Water Oxidation Catalysts

The Hill lab has pioneered the development of efficient, stable, homogeneous molecular catalysts for visible light-driven water oxidation using polyoxometalates (POMs). Recent studies have characterized the catalytic activity and stability of POMs containing ruthenium, cobalt, and nickel centers.
