摘要：

A novel pi-pi* conjugate system photo-catalyst was successfully constructed using aniline, pyrrole and TiO2. The structures of photo-catalyst were measured by XRD, SEM, BET, TEM, FT-IR, XPS and TGA in detail. The photocatalytic properties were investigated in rhodamine B and methyl orange solution, respectively. And the enhance mechanism of pi-pi* conjugate system was discussed in depth. The weight percentage of Ti weight about 47% in the compound and the pi-pi* conjugate system did not change the crystal structure of TiO2. The photocatalytic degradation properties of the pi-pi* conjugate system photo-catalyst could get 99% for rhodamine B and methyl orange after 10 and 15 min, respectively. The introduction of the pi-pi* conjugate system into TiO2 was beneficial to improve light harvest, photoelectric response and separation of electron-holes.
