Title

Enhanced Visible Light Conversion Efficiency Using Nanocrystalline WO3 Films

Authors
Published in Advanced Materials. 2001, vol. 13, no. 7, p. 511-514
Abstract Drastically improved photooxidation efficiencies,when compared to bulk WO<sub>3</sub>, are obtained with nanocrystalline WO<sub>3</sub> films (see Figure) deposited from a colloidal solution of tungstic acid. Saturation of the photocurrent, which occurs even for moderate potential differences, indicates a completely different mechanism of charge separation. The electrodes should be highly effective for photoelectrolysis of water by sunlight.
