Three-dimensional porous MoS nanobox embedded g-CN@TiO architecture for highly efficient photocatalytic degradation of organic pollutant.

Herein, a simple, highly efficient and stable MoS nanobox embedded graphitic-CN@TiO (g-CN@TiO) nanoarchitecture was synthesized by a facile solvothermal approach. The nano-hybrid photocatalyst was constructed by TiO nanoparticles anchored on the surface of g-CN nanosheets. Then highly crystalline three-dimensional porous MoS nanobox was homogeneously distributed on the g-CN@TiO surface. The g-CN@TiO/MoS hybrid achieved a high photocatalytic degradation efficiency of 97.5% for methylene blue (MB) dye pollutant under visible-light irradiant in an hour which was much better than TiO@MoS g-CN@TiO MoS TiO and g-CN. Furthermore, the reaction rate (k) value of g-CN@TiO/MoS for MB dye is as high as 3.18 X 10 min, which is ~ 2.65 times better than those of g-CN@TiO and MoS. This work presents a rational structure design, interfacial construction and suitable band gap strategy to synthesize advanced nano-hybrid photocatalyst for degradation of organic pollutant with excellent performance and long-term stability.
