| 英文摘要 | It is revealed that TiO2 nanotube confined Pd nanoparticles (Pd-in-TiO2NT) processed better photocatalytic degradation activity than Pd nanoparticles loaded on outer wall of TiO2 nanotube (Pd-out-TiO2NT). Moreover, by anchoring Fe2O3 nanoparticles on Pd-in-TiO2NT (Pd-in/Fe2O3-TiO2NT), the photocatalytic activity is dramatically improved as evidenced by the accelerated photocatalytic degradation of methyl orange. As measured by photoluminescence and electrochemical impedance spectroscopy, the separation efficiency of photogenerated electron-hole pairs is significantly improved when the outside surface of TiO2NT was modified by Fe2O3. X-ray photoelectron spectroscopy informs that the Fe2O3 modification can efficiently modulate the electron density distribution of the TiO2 nanotube, thus improves the catalytic oxidation of Pd in Pd-in/Fe2O3-TiO2NT. This work provides a novel method to construct high active catalysts for environmental prevention by the modulation of electronic state on TiO2 nanotube confinement effect. |
