A photocatalyst of nanometer TiO_2/conjugated polymer complex was successfully synthesized and characterized by spectro- scopic methods and photocatalytic experiments.The complex photocatalyst could be activated by absorbing both ultraviolet and visible light(λ=190-800 nm).Methylene blue(MB)could be degraded more efficiently on the complex photocatalyst than on the TiO_2 under natural light.The conjugated polymer played a promoting role in the photocatalytic degradation of MB.The calcination temperature had an important effect in degradation of dye and could be summarized as 260℃>300℃>340℃>220℃>180℃.
