However, the strong demand for a high H<inf>2</inf> production rate will present conflicting requirements of excellent photoactivity and low-cost photocatalysts. The first alternative may be abundant nanostructured titanate-related materials as a photocatalyst. Here, we report highly dispersed Na<inf>2</inf>Ti<inf>3</inf>O<inf>7</inf> nanotubes synthesized via a facile hydrothermal route for photocatalytic degradation of Rhodamine B (RhB) and the water splitting under UV-visible light irradiation. Compared with commercial TiO<inf>2</inf>, the nanostructured Na<inf>2</inf>Ti<inf>3</inf>O<inf>7</inf> demonstrated excellent photodegradation and water splitting performance, thus addressing the need for low-cost photocatalysts. The as-synthesized Na<inf>2</inf>Ti<inf>3</inf>O<inf>7</inf> nanotubes exhibited desirable photodegradation, and rate of H<inf>2</inf> production was 1,755 μmol·g⁻¹·h⁻¹ and 1,130 μmol·g⁻¹·h⁻¹ under UV and simulated solar light irradiation, respectively; the resulting as-synthesized Na<inf>2</inf>Ti<inf>3</inf>O<inf>7</inf> nanotubes are active in UV light than that of visible light response.falseHydrogen Evolution | Na2Ti3O7 | Photocatalysts | Pollutants | Renewable EnergyArticle1019-10251 April 201816arJournal15
