Enhanced Patterned Cocatalyst TiO(2)/Fe(2)O(3) Photoanodes for Water-Splitting

In this study, we used a hot-pressing process to enhance the photocatalytic properties of TiO(2)/Fe(2)O(3) bimetallic oxide with a periodic patterned structure on the surface to increase photon absorption for photocatalysis in the oxygen evolution reaction for water splitting. The hot-pressed sample...

Sumario:In this study, we used a hot-pressing process to enhance the photocatalytic properties of TiO(2)/Fe(2)O(3) bimetallic oxide with a periodic patterned structure on the surface to increase photon absorption for photocatalysis in the oxygen evolution reaction for water splitting. The hot-pressed samples show that combining the two metal oxides improves the absorption band edge of the electrode at different wavelengths. The patterned structure obtained using the hot-pressing process successfully improves photon absorption, resulting in a two-fold enhancement compared with a flat surface electrode.
