In any artificial photosynthetic system, the oxidation of water to molecular oxygen provides the electrons needed for the reduction of protons or carbon dioxide to a fuel. Understanding how this four-electron reaction works in detail is important for the development of improved robust catalysts made of Earth-abundant materials, like first-row transition-metal oxides. Here, using time-resolved Fourier-transform infrared spectroscopy and under reaction conditions, we identify intermediates of water oxidation catalysed by an abundant metal-oxide catalyst, cobalt oxide (Co3O4).

- A new method is introduced for creating Ni and Cu2O nanocubes, sized between 200-500 nm, using a templated electrodeposition technique on cubic PMMA templates.
- This approach not only simplifies the production of the templates but also holds the potential to be cost-effective when scaled up.
- The resulting p-Cu2O nanocubes show improved photocatalytic activity for solar water splitting compared to traditional thin films, making them a promising material for energy applications.
Article Synopsis
- Developing efficient nanostructured photoelectrodes requires precise control over morphology and electrical conductivity.
- A new plasma-processing technique creates porous structures in tungsten, which, after a two-step annealing, turns into photoactive monoclinic WO3.
- This method allows for excellent size control and crystallite contact, paving the way for advanced nanostructured materials suitable for applications like solar water splitting.
