Enhanced Photocatalytic Activity for Titanium Dioxide in Sunlight by a Kind of Squarylium Cyanine Dye

摘要：

The research synthesized bis-(2-methyl quinoline) squarylium cyanine (abbr.QYCD).it was used as dye to enhance the photocatalytic activity of nano-TiO2 in sunlight.Then the photocatalytic process of removal of benzene was investigated indoor air.Results reveal that bis-(2-methyl quinoline)- squarylium cyanine has an intense absorption in the light region of 200nm -800 nm.The Benzene removal of QYCD-nano-TiO2 complex catalyst at 78h was 97.69％,at the same time it was 36.96％ higher as compared with that of nano-TiO2.

关键词： Squarylium cyanine Photosensitive TiO2.
