The coordination of multiple materials is an effective strategy to develop high-performance sensing material, which requires a profound understanding of the structure-function relationship between multiple materials. Herein, a novel electrode material that reduced graphene oxide@Co3O4-N-doped carbon (rGO@Co3O4-NC) jungle has been formed on the surface of indium tin oxide (ITO) by the proposed in-situ preparation method. The template-directed growth of zeolitic imidazolate framework-67 (ZIF-67) is performed in a confined preparation process. The rGO@Co3O4-NC/ITO electrode with a unique structure based on two-dimensional nanosheets is eventually fabricated by a pyrolysis process of precursor. Such rGO@Co3O4-NC/ITO electrode can be directly used as a working electrode to establish an electrochemical sensor. The non-enzymatic glucose sensor based on rGO@Co3O4-NC/ITO exhibits good performances including the sensitivity of 2563 mu A mM(-1) cm(-2), the detection limit of 50.4 nM, and the linear detection range of 0.5 mu M-20.0 mu M (R = 0.9992). The performance benefits of rGO@Co3O4-NC have been considered to be attributed to the structural and compositional advantages of ternary materials. This work represents the structure-function relationship of rGO, Co3O4 and NC, which is helpful for the design of multiple materials.
