Enhanced Visible Light Conversion Efficiency Using Nanocrystalline WO3 Films

Published in Advanced materials. 2001, vol. 13, no. 7, p. 511-514
Abstract Drastically improved photooxidation efficiencies,when compared to bulk WO3, are obtained with nanocrystalline WO3 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.
