| Popis: |
Ag doped TiO2 whiskers were synthesized by calcining metatitanic acid with potassium car= bonate to form tetratitanate whisker precursor, following by proton-exchanged and immobilized with Ag+. The post treatment conditions for whiskers synthesis were investigated and the phase composition, morphology and photocatalytic performance were characterized. The results showed that the TiO2 whiskers had an aspect ratio more than 15 and the absorption edge of Ag doped titania whiskers were red shifted to 50 nm. The result of methylene blue degradation revealed that the photocatalytic performance of Ag doped TiO2 whisker has been greatly improved. |
