β-cyclodextrin grafted titanium dioxide (β-CD/TiO2) was synthesized through photo-induced self assembly methods in this work. After being modified by β-CD, the photocatalytic activities of TiO2 samples increased by 2.3 times the degradation of paracetamol under visible light irradiation. The decrease trend in final degradation efficiency was 10 % after three repetitive experiments. According to present and published results, β-CD/TiO2 possesses great potential to be an effective and stable catalyst. Mechanism of photocatalysis with β-CD/TiO2 is also proposed.
