Fund Project: Financial supports from the National Natural Science Foundation of China (Nos.30571536 and 20677019) are gratefully acknowledged.The Center of Analysis and Testing of Huazhong University of Science and Technology is thanked for characterization of Fe (OH)₃/TiO₂ catalysts.

A very simple and controllable approach was proposed to synthesize novel Fe(OH)₃/TiO₂ nanoparticles. Compared with neat TiO₂, the Fe(OH)₃/TiO₂ increased the rate of the photocatalytic degradation of methyl orange at pH 6.0 by more than five times, showing photocatalytic activity as excellent as P25. This enhancing effect is mainly attributed to the ferric hydroxide deposits as the electron scavenger and the enriched surface hydroxyl groups.
