【Abstract】 Nano-TiO2 photocatalyst co-doped with boron(B) and fluorine(F) was prepared, the polystyrene(PS) matrix composite was synthesized also, and accelerated photodegradation experiment was accomplished. The changes of the surface morphology of thin sample plate were characterized by SEM, and the phase change temperature in the process of degradation was detected by DSC. The result shows that the photodegradation efficiency of TiO2 co-doped with boron and fluorine to PS was improved.更多还原
