Paper Title:
Preparation and Photodegradation of Humic Acid by a Y3+-Doped ZnO/TiO2 Composite
  Abstract

Aim to remove soluble humic acid (HA) in super-critical boiler make-up water, Y3+-doped ZnO/TiO2 composites were prepared using a solid-phase synthesis method, Their properties were characterized by x-ray diffraction, transmission electron microscopy, and UV-visible diffuse reflection spectroscopy (DRS); their visible light photoactivities were evaluated by the photodegradation of humic acid in an aqueous solution under sunlight irradiation.. The experiment results showed that Y3+-doped samples had a higher absorbance than pure TiO2, and a red shift appeared in the DRS spectrum; The Y3+-doped ZnO/TiO2 multiplex nanocomposite can expand the wavelength range for light absorption and increase the sunlight utilization efficiency. Samples with 3% Y3+ and 27% ZnO have the highest photoactivities.
