Carbon nanomaterials with a different character of the chemical bond—graphene (sp2) and nanodiamond (sp3)—are the building bricks for a new class of all-carbon hybrid nanomaterials, where the two different carbon networks with sp3 and sp2 hybridization coexist, interacting and even transforming into one another. The extraordinary physiochemical properties defined by the unique electronic band structure of the two border nanoallotropes ensure the immense application potential and versatility of these all-carbon nanomaterials. The review summarizes the status quo of sp2 – sp3 nanomaterials, including graphene/graphene-oxide—nanodiamond composites and hybrids, graphene/graphene-oxide—diamond heterojunctions, and other sp2–sp3 nanocarbon hybrids for sensing, electronic, and other emergent applications. Novel sp2–sp3 transitional nanocarbon phases and architectures are also discussed. Furthermore, the two-way sp2 (graphene) to sp3 (diamond surface and nanodiamond) transformations at the nanoscale, essential for innovative fabrication, and stability and chemical reactivity assessment are discussed based on extensive theoretical, computational and experimental studies.

“…Nitrogen-incorporated ovoid-shaped nanodiamond (NOND) is a carbon material with excellent biomedical sensing properties, especially as it relates to DA sensing, owing to its excellent biocompatibility and protein adsorption capacity after special treatment. , Additionally, NOND possesses excellent chemical and mechanical properties, a wide working potential window (−1.5 to 1.5 V), and a low background current, which are advantageous for electrochemical sensing. , Through the incorporation of nitrogen into the structure in the microwave plasma-enhanced chemical vapor deposition (MPECVD) process, the sp 2 /sp 3 can be adjusted to a higher ratio so that the NOND films can exhibit high conductivity. , Moreover, the trans-polyacetylene sp 2 bonds and amorphous graphite structure at the grain boundaries of the NOND , enable NOND to detect the corresponding redox peaks of DA, AA, and UA …”

Nitrogen-incorporated ovoid-shaped nanodiamond (NOND) film exhibits excellent electrochemical sensing properties owing to its unique characteristics. In this study, to improve the sensitivity of NOND-based biosensors for dopamine (DA) detection, a detailed investigation concerning the growth mechanism of NOND films was conducted, it is found that the NOND films did not directly grow on a Si substrate during the growth process but preferentially originated from the formation of a thin Si3N4 interlayer attributed to the reactions of Si substrate and nitrogen atoms in the plasma in the very early stage of deposition. Subsequently, the diffusion of nitrogen from the inner Si3N4 to the Si3N4/plasma interface produces more active sites for the adsorption of the ionized carbon atoms. As the process proceeded further, the growth of ovoid-shaped diamonds accompanies the decrease of the Si3N4 interlayer thickness owing to the diffusion of nitrogen from Si3N4. Significant Si3N4 peaks are observed from both the Raman and X-ray diffraction analyses when the sample was subjected to NOND deposition for less than 20 min. These peaks then completely disappeared after deposition for 60 min, demonstrating the proposed mechanism. Furthermore, it is also observed that the deposition of the Si3N4 interlayer increased the hydrophilicity of the substrate, which is ascribed to the lower surface free energy of the NOND. To enhance the sensitivity of the NOND, the synthesis of NOND with patterned arrays (P-NOND) is proposed. The high specific surface area of the highly hydrophilic P-NOND obviously enhances the sensitivity of the P-NOND-based electrodes. Application of the P-NOND electrode for DA detection is successfully demonstrated in the mixed DA electrolyte, showing a better performance than that of the pristine NOND. This work reveals that the P-NOND electrode possesses superior sensitivity and selectivity, which is very favorable for DA sensing.

Carbon nanomaterials with a different character of the chemical bond – graphene (sp2) and nanodiamond (sp3) are the building bricks for a new class of all-carbon hybrid nanomaterials, where the two different carbon networks with the sp3 and sp2 hybridization coexist, interact and even transform into one another. The unique electronic, mechanical, and chemical properties of the two border nanoallotropes of carbon ensure the immense application potential and versatility of these all-carbon graphene – diamond nanomaterials. The review gives an overview of the current state of the art of graphene – diamond nanomaterials, including their composites, heterojunctions, and other hybrids for sensing, electronic, energy storage, and other applications. Also, the graphene-to-diamond and diamond-to-graphene transformations at the nanoscale, essential for innovative fabrication, and stability and chemical reactivity assessment are discussed based on extensive theoretical, computational, and experimental studies.
