Abstract

The composites of low band gap donor-acceptor-donor(D-A-D) type conjugated polymer containing pyridine units:poly(2

5-bis(2-(3

4-ethylenedioxythiophene)) pyridine) with Ti O2 hollow microspheres(the mass ratio of monomer(2

5-bis(2-(3

4-ethylenedioxythiophene)) pyridine) to Ti O2 is 1︰2

1︰3 and 1︰4 in the reaction system) was prepared

and the photocatalytic activity of this type of composite materials were studied.The structure and morphology of the composite materials were characterized by Fourier transform infrared spectroscopy(FT-IR)

X-ray diffraction(XRD)

scanning electron microscope(SEM) and transmission electron microscope(TEM).The results showed that the Ti O2 hollow microspheres had anatase phase structure

and their surface was loaded by poly(2

5-bis(2-(3

4-ethylenedioxythiophene)) pyridine).It was found that the rate of photocatalytic degradation of Rhodamine B by composite was the highest under simulated sunlight irradiation

when the mass ratio of monomer to Ti O2 was 1︰3

and the highest degradation rate of Rhodamine B was 92.1%after 240 min

which proved that the combination of polymers improves the photocatalytic performance of Ti O2 hollow microspheres.
