Hierarchical Ultrathin Layered GO-ZnO@CeO Nanohybrids for Highly Efficient Methylene Blue Dye Degradation.

Highly efficient interfacial contact between components in nanohybrids is a key to achieving great photocatalytic activity in photocatalysts and degradation of organic model pollutants under visible light irradiation. Herein, we report the synthesis of nano-assembly of graphene oxide, zinc oxide and cerium oxide (GO-ZnO@CeO) nanohybrids constructed by the hydrothermal method and subsequently annealed at 300 °C for 4 h. The unique graphene oxide sheets, which are anchored with semiconducting materials (ZnO and CeO nanoparticles), act with a significant role in realizing sufficient interfacial contact in the new GO-ZnO@CeO nanohybrids.

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.
