A green and simple strategy to prepare graphene foam-like 3D porous carbon/NiNPs nanocomposites was developed.
The pomelo peel was employed to construct the graphene foam-like 3D porous carbon/NiNPs nanocomposites.
The NiNPs was acted as the catalyst to result in the formation of graphene foam-like 3D porous carbon.
The nanocomposites were used to construct glucose electrochemical sensor and exhibited a good performace.
