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.

“…Real-time monitoring of Pb 2+ content in seawater is a primary approach to prevent risk associated with Pb 2+ [ 50 , 51 , 52 ]. We propose using a metal-catalyzed in-situ grown graphene film to develop a graphene modified self-supported boron-doped diamond electrode (G/SBDD) to detect Pb 2+ in seawater [ 53 ]. Compared with the unmodified SBDD (Self-Supported Boron-Doped Diamond Electrode), G/SBDD enables the detector to display both superior sensing performance (high conductivity, high electrochemical active area) and detection performance (high sensitivity, low detection limit, high selectivity).…”

Graphene films made by chemical vapor deposition (CVD) are a popular method to modify sensors by virtue of large-scale and reproducibility, but suffer from various surface contamination and structural defects induced during transfer procedures. In-situ growth of graphene films is proposed in this review article to improve sensing performance. Root causes of the surface contamination and structural defects are revealed with several common transfer methods. In-situ approaches are introduced and compared, growing graphene films with clean surfaces and few defects. This allows graphene film to display superior sensing performance for sensor applications. This work may reasonably be expected to offer a good avenue for synthesis of graphene films applicable for sensing applications.

“…Як підкладку для АДБ-плівок використовують високопровідний кремній з шаром SiO 2 товщиною 2 мкм. Для отримання модифікацій поверхні алмазу використовують також нанокластери золота, нікелю, бісмуту, cажі, нафіону, графену тощо [40][41][42][43][44][45]. Для зменшення дефектів поверхні АДБЕ часто використовують вакуумний підпал та оброблення водневою плазмою in situ [46].…”
