Direct Synthesis of Reduced Graphene Oxide/TiO₂ Nanotubes Composite from Graphite Oxide as a High-Efficiency Visible-Light-Driven Photocatalyst.

Synthesis of reduced graphene oxide/TiO₂ nanotubes (rGO/TNTs) composite is being attended. However, the synthesis of rGO/TNTs composite directly from graphite oxide with a greener approach is still challenging. In this study, we directly synthesized rGO/TNTs composite by a simple method from graphite oxide and titanium dioxide nanotube (TNTs) powder without involving any assistant agents.
