英文摘要	The optical property of TiO2 plays an important role in its various and promising photocatalytic applications. Previous efforts in improving its optical properties include doping with various metal and/or non-metal elements, coupling with other colorful semiconductors or molecules, and hydrogenating to crystalline/disordered core/shell nanostructures. Here, we report a beautiful green TiO2 achieved by forming the charge-transfer complex of colorless hydrazine groups and surface Ti4+, which extends the optical absorption into the near infrared region (approximate to 1100 nm, 1.05 eV). It shows an enhanced photocatalytic performance in hydrogen generation under simulated sunlight, and degradation of organic pollution under visible light due to an impurity state (about 0.28 eV) resulting in fast electron-hole separation and injection of electrons from the ligand to the conduction band of TiO2. This study demonstrates an alternative approach to tune the optical, impurity state and photocatalytic properties of TiO2 nanoparticles and we believe this will spur a wide interest in related materials and applications.
