“…Taking advantage of the Ni-assisted diamond transformation, Tsubota et al proposed a new simple method for fabricating a microchannel covered with a GN layer on a diamond substrate [63]. Also, Ni/Fe catalyst-assisted process in a vacuum induction furnace enables growth of GN nanowalls directly on diamond particles [64].…”

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.

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.

Carbon has around 500 allotropes, and most of them have excellent physical properties offering great potential for the development of electronic, optoelectronic, energy storage, and sensor applications. In the case of diamond and graphene/graphite, although the carbon atoms have different hybridization structures, their complementary characteristics and potential for direct conversion between them may open up opportunities for novel all-carbon device applications. Diamond and graphene/graphite have unique superior properties and good lattice matching between them so that the direct fabrication of high-quality graphene-on-diamond heterostructures enables the new development of a variety of ultrawide bandgap devices and chemical/bio-sensors. In this perspective, we introduce recent investigations into the formation of graphene films on diamond substrates through an in situ sp3-to-sp2 conversion process to enable their application to radiation detection/photo-electronics, high-power/high-frequency electronics, and chemical/biological sensing.
