Incorporation of graphene oxide in quantum dot sensitized photocatalyst based on ZnO nanorods. 2014

Jinzhao Huang, and Yongdan Zhao, and Song Liu, and Lei Kuang, and Tao Jiang, and Shiyou Liu, and Mingzhi Wei

The novel efficient architecture of photocatalyst is fabricated by incorporating graphene oxide (GO) in quantum dots (QDs) sensitized ZnO nanorods and the photocatalytic properties for methyl orange (MO) degradation are investigated by scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), UV-vis-NIR absorption spectroscopy. The results indicate that the incorporating of grapheme oxide is more favourable for the degradation. The improved photocatalytic properties can take several advantages given that the higher carrier mobility of GO which can reduce the recombination of carriers, and assembled quantum dots which can facilitate the absorption of solar light. The paper provides the clue to design the effective and easy recyclable photocatalyst.
