A cobalt-based water oxidation catalyst may be grown from sputter-deposited thin films (800 nm thick) of cobalt metal on a
non-conductive glass substrate. Chemical composition and function of the
catalyst prepared in this manner are similar to that for catalyst films
prepared by electrodeposition of the catalyst from aqueous solutions of
Co2+ salts. The method permits water oxidation catalysis to be established
from protective barrier layers on materials that otherwise experience
corrosion under the aqueous oxidative conditions.
