ZnFe2O4 multi-porous microbricks/graphene hybrid photocatalyst: Facile synthesis, improved activity and photocatalytic mechanism

- A new hybrid photocatalyst of ZnFe2O4 multi-porous microbricks/graphene is successfully prepared by a facile two-step strategy.
- The hybrid exhibits enhanced photocatalytic activity for degradation of 4-CP under visible light irradiation.
- Graphene supplies intimate interfacial contact and efficient charge separation.
- Transfer of photogenerated charge carriers and photocatalytic mechanism on hybrid is proposed.
