| Abstract: | Flaky monoclinic La2Ti2O7 was prepared via a hydrothermal method based on the reaction of Ti(SO4)2 and La(NO3)3. Relative to the solid-state reaction sample, the flaky La2Ti2O7 showed higher surface areas, much smaller crystal size and more efficient light absorption. All these factors led to the higher photoactivity to produce H2 from water splitting under UV irradiation. |
