Degradation of Humic Acid Using a CdS/TiO₂ Nanotubes Electrode

Abstract:

Use NH₄F as the electrolyte, prepared TiO₂ nanotubes which orderly arranged by anodic oxidation. CdS was load to the TiO₂-nanotubes by using chemical deposition method, then controlled size of CdS particles and uniformly load had been found when the EDTA-2NA was mixed in. The structure and morphology of TiO₂ nanotubes and modified TiO₂ nanotubes were observed by SEM. Use humic acid as simulate pollutant, investigate the efficiency of the CdS / TiO₂nanotubes photocatalytic oxidation of organic compounds .The results show that CdS modified TiO₂nanotubes arrays after added EDTA-2NA, the degradation rate of humic acid increased from 57.1 % to 85.4 % after illumination.
