TiO₂/ Graphene Nanotube Arrays with Enhanced Photoelectric Properties

Abstract:

Highly ordered TiO₂ nanotube arrays were prepared by two-step anodic oxidation, and the graphene was assembled on them via the solvothermal method. The photoelectric performance was investigated, the results indicated the TiO₂/rGO nanocomposites with higher photocurrent response compared with pure TiO₂, and the cyclic voltammetry of the TiO₂/rGO at different scan rates of 10 to 200 mV/S showed a good electrochemical capacitance. The crystal structure, morphology, and chemical composition of the samples were also characterized by XRD, SEM, and XPS.
