Fabrication and photocatalytical enhancement of ZnO-graphene hybrid using a continuous solvothermal technique

- A continuous solvothermal route for producing ZnO-graphene composites is developed.
- Two different structures of ZnO-graphene, a film-grain and a cobweb, are obtained.
- The synthesis mechanism of ZnO-graphene in solvothermal media is illustrated.
- ZnO-graphene exhibits excellent photocatalytic activity in degrading methyl orange.
