Graphene-based nanohybrid is considered to be the most promising nanomaterial for electrochemical sensing applications due to the defects created on the graphene oxide layers. These defects provide graphene oxide unique properties, such as excellent conductivity, large specific surface area, and electrocatalytic activity. These unique properties encourage scientists to develop novel graphene-based nanohybrids and improve the sensing efficiency. This review, therefore, addresses this topic by comprehensively discussing the strategies to fabricate novel graphene based nanohybrids with high sensitivity. The combinations of graphene with various nanomaterials, such as metal nanoclusters, metal compound nanoparticles, carbon materials, polymers and peptides, in the direction of electrochemical sensing, were systematically analyzed. Meanwhile, the challenges in the functional design and application of graphene-based nanohybrids were described and the reasonable solutions were proposed.

Probing Interface Manipulation of Metal‐Graphene Composites via Doping and Vacancy Engineering towards Excellent Mechanical Strengths

Owing to the unique merits benefited from the two‐dimensional (2D) geometry, graphene has been often chosen as an attractive strength enhancer during the design of metal‐graphene structural composites. In spite of the improved mechanical properties with the assistance of graphene, it is still challenging to fit the strength requirements for these metal‐graphene composites in the practical applications. To address this issue, metal‐doping and carbon‐vacancy engineering, in this work, are first proposed to manipulate the dual‐phase interfaces between metal and graphene in order to further strengthen the mechanical properties in metal‐graphene composites based on the first‐principle calculation. It can be concluded that a single‐carbon‐vacancy graphene or a Ti, Mn‐doped metal matrix in metal‐graphene composites delivers the best interfacial binding capability, resulting in an obvious strength increase of over 110% for Cu‐graphene composites. Finally, the deformation mechanisms of metal‐graphene composites are discussed via the evaluation on tensile deformation processes, electron densities, and stacking fault energies. This work offers us an alternative solution for the effective reinforcement on mechanical properties of metal‐graphene composites by manipulating the dual‐phase interfaces using doping or vacancy engineering.
