摘要

Polythiophene (PTh) nanosheets and spheres were successfully synthesized by changing the oxidation ability of ferric ions without any templates. Their distinct morphologies caused by different growth processes lead to different photo-catalytic activity for methylene blue (MB) degradation under visible light. The mechanism of morphology performance relationship was thoroughly studied. It shows that different morphologies are the reflection of different length and bond connection of PTh chains, which are the real reasons for different performance.
