Reducing the high recombination rate and the band gap of titania is vital and valuable for improving its photocatalytic activity.Herein, anatase (A) nanoslice and amido-grafted graphene oxide (AGO) nanocomposite with an armor structure were designed and prepared by a solvothermal method, in which the formation of the armor structure and nitrogen (N) doping into A nanoslice were carried out in one-pot successfully.The characterization results of the nanocomposites show that N doped Collections A nanoslices with an average size of 7.

8 nm and dominant {001} facets are distributed uniformly on the surface of AGO.The photocatalytic activity Lid Lock Assembly of the AGO-A nanocomposite is significantly enhanced by the combination of A nanoslice with AGO.Typically, the reaction rate constant of the nanocomposite is 3.

34 times higher than that of A nanoslice.These can be ascribed to the synergistic effects among the armor structure, A nanoslice with dominant {001} facets, enhanced adsorption ability by AGO, N doped A nanoslice and excited electron transfer from A nanoslice to AGO.Furthermore, a mechanism on the enhancement of the photocatalytic activity of the nanocomposite is proposed.

These provide new insights for designing and preparing the nanocomposite photocatalysts with novel structure and enhanced activity.
