Synthesis of Tungsten-Cerium Doped Titanium Oxide Nanocatalyst to Remediate Water by the Degradation of Atrazine Herbicide

摘要: Tungsten (W) and Cerium (Ce) doped nanoTitanium oxide (TiO 2) nanophotocatalyst were prepared by the sol-gel method and their photodegradation effect against atrazine herbicide were investigated. The doping of the nanocatalyst took place at 50 C within a time interval of 120 minutes. The prepared gel was dried and calcined in the oven at 350 C for 75 minutes. The XRD result revealed that the synthesized nanocatalyst was 16.7 nm in size with a mostly monoclinic structure. With FTIR spectra, characteristic peaks of TiO 2 were found at 516 cm-1, Ti-O-Ce at 1104 cm-1, and WO with a single bond at 1609 cm-1. Scanning electron microscope analysis revealed the surface morphology of synthesized nanophotocatalyst. The photocatalytic activity of synthesized nanocatalyst was tested on the degradation of atrazine herbicide (ATZ) under visible and UV light in a batch reactor. The efficiency of nanocatalyst was …
