中文摘要	Ag doped TiO/sub 2/ whiskers were synthesized by calcining metatitanic acid with potassium carbonate to form tetratitanate whisker precursor, following by proton-exchanged and immobilized with Ag/sup + /. The post treatment conditions for whiskers synthesis were investigated and the phase composition, morphology and photocatalytic performance were characterized. The results showed that the TiO/sub 2 / 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 TiO/sub 2/ whisker has been greatly improved.
