The results demonstrate that β-BiTaO4–methylene blue presented photocatalytic activity with respect to hydrogen production, which opens up prospects for improving systems that are able to drive photocatalytic reaction with visible light illumination to make effective use of solar light (∼45% of visible light) to produce hydrogen from water.Submitted by Edileide Reis (leyde-landy@hotmail.com) on 2014-07-10T13:15:21Z No. of bitstreams: 1 I.
