英文摘要	As a new member of carbon dots (CDs), Polymer dots (PDs) prepared by hydrothermal treatment of polymers, usually consist of the carbon core and the connected partially degraded polymer chains. This type of CDs might possess aqueous solubility, non-toxicity, excellent stability against photo-bleaching and high visible light activity. In this research, PDs were prepared by a moderate hydrothermal treatment of polyvinyl alcohol, and PDs grafted TiO2 (PDs-TiO2) nanohybrids with Ti-O-C bonds were prepared by a facile in-situ hydrothermal treatment of PDs and Ti (SO4)(2). Under visible light irradiation, the PDs TiO2 demonstrate excellent photocatalytic activity for methyl orange degradation, and the photo catalytic rate constant of PDs-TiO2 is 3.6 and 9.5 times higher than that of pure TiO2 and commercial P25, respectively. In addition, the PDs TiO2 exhibit good recycle stability under UV-Vis light irradiation. The interfacial Ti-O-C bonds and the pi-conjugated structures in PDs-TiO2 can act as the pathways to quickly transfer the excited electrons between PDs and TiO2, therefore contribute to the excellent photocatalytic activity.
