Fe-doped TiO2 with rich surface oxygen vacancies was prepared by a facile solvothermal method combined with HF etching. The doping of Fe extends the light absorption range of TiO2 from ultraviolet to visible light. The abundant oxygen vacancies on the TiO2 surface cooperate with the d orbital of Fe3+ to provide a large number of active sites for activating nitrogen molecules, and inhibit the recombination of electrons and holes. In ambient condition, without any sacrificial agent, the ammonia production of 6% Fe-TiO2 reaches 94.3 µmol·g-1·h-1, compared to that of pure TiO2. In visible light illumination, the ammonia production of 6% Fe-TiO2 reaches 45.6 µmol·g-1·h-1.
