Abstract

Article history: The reduced TiO nanobelts are prepared through reduction of pure nanobelts by utilizing NaBH . 2 4 Received 4 August 2015 Compared with pure TiO nanobelts, the reduced TiO nanobelts present enhanced UV and visible photo- 2 2 Received in revised form 2 November 2015 catalytic performance in decomposing methyl orange (MO) and water splitting for hydrogen production. Accepted 6 November 2015 Experimental results and theoretical calculations show that the improved performance is due to the Available online 10 November 2015 3+ generation of Ti and oxygen vacancy, which can increase the visible light absorption, promote charge carrier trapping, and improve photogenerated electron–hole separation efficiency, thus the photocat- Keywords: 3+ alytic property is improved. Moreover, the reduced TiO nanobelts with high ratio of Ti (55.8%) present NaBH reduction 3+ better photocatalytic properties than that of reduced TiO nanobelts with lower ratio of Ti (9.8%), which TiO nanobelts 3+ indicates that a certain high ratio of Ti will facilitate photocatalysis. The results show that the reduced Photocatalytic 3+ TiO represent an effective strategy in improving the visible photocatalytic properties. Ti ions 2 UV–visible © 2015 Elsevier B.V.
