Au nanoparticles and reduced graphene oxide co-loaded TiO2 nanotube arrays (Au/RGO-TiO2 NTs) were prepared through a simple one-step constant-potential electrolysis of chloroauric acid and graphene oxide on TiO2 NTs. Compared with Au-TiO2 NTs, RGO-TiO2 NTs and un-modified TiO2 NTs, the Au/RGO-TiO2 NTs exhibited high efficiency in photocatalytic degradation of methyl orange (MO) under simulated solar light irradiation. The highly efficient photocatalytic activity is associated with broad absorption in the visible light region, increased photoinduced charge separation through transferring photogenerated electrons from TiO2 NTs to both Au and RGO, as well as the strong adsorption ability of RGO to MO molecules. Moreover, the Au/RGO-TiO2 NTs has an excellent stability. This work provides an insight into designing and synthesizing new TiO2 NTs-based hybrid materials for effective visible light-activated photocatalysis. (c) 2013 Elsevier B.V. All rights reserved.
