摘要: TiO2 coated Au nanoparticles were synthesized and characterized by TEM, XPS XRD. It was found that the with thus forming a core-shell structure. Electron transfer, adsorption photodegradation of malonic acid on catalyst investigated in situ attenuated total reflection infrared (ATR-IR) spectroscopy. Malonic adsorbed underwent efficiently air nitrogen atmosphere under UV light illumination prepared catalyst. As intermediate species oxalate observed surface during acid. The accelerate degradation capturing conduction band electrons TiO2. ATR spectra also reveal interface electron transfer from to visible illumination. (C) 2012 Elsevier B.V. All rights reserved.
