Sub-nano CoOx attached onto WO3 for efficient photocatalytic and photoelectrochemical water oxidation

Here, a facile strategy is reported for attaching a sub-nano cobalt oxide catalyst onto a WO3 surface using Co-EDTA as precursor, which greatly improved the WO3 performance in OER to give a photocatalytic O2 evolution rate of 314.3 μmol h−1 and a photocurrent density of around 2.07 mA cm−2 at 1.3 V...

Summary:Here, a facile strategy is reported for attaching a sub-nano cobalt oxide catalyst onto a WO3 surface using Co-EDTA as precursor, which greatly improved the WO3 performance in OER to give a photocatalytic O2 evolution rate of 314.3 μmol h−1 and a photocurrent density of around 2.07 mA cm−2 at 1.3 V vs. Ag/AgCl in photoelectrochemical water oxidation.
