One-step reduction and functionalization protocol to synthesize polydopamine wrapping Ag/graphene hybrid for efficient oxidation of hydroquinone to benzoquinone

- One-step reduction synthesis of polydopamine wrapping RGO/Ag hybrid is described.
- Polydopamine acts as functionalization and simultaneous reduction.
- The PDA-Ag-RGO hybrid exhibits good dispersivity in polar solvents.
- The hybrid has superior catalytic activity for hydroquinone oxidation.
- The hybrid keeps superior catalytic activity over multiple cycles.
