Microwave-Hydrothermal Tuning of Spinel-Type Co ₃ O ₄ Water Oxidation Catalysts.

ABSTRACT: Water oxidation is the bottleneck reaction for overall water splitting as a direct and promising strategy toward clean fuels. However, the development of robust and affordable heterogeneous water oxidation catalysts remains challenging, especially with respect to the wide parameter space of synthesis and resulting material properties. Oxide catalysts performance in particular has been shown to depend on both synthetic routes and applied catalytic test methods. We here focus on spinel-type Co₃O₄ as a representative case for an in-depth study of the influence of rather subtle synthetic parameter variations on the catalytic performance. To this end, a series of Co₃O₄ samples was prepared via time-saving and tunable microwave-hydrothermal synthesis,
