• gold in ethanol. They proposed that both the gold target and ethanol have a fundamental impact on the carbyne formation. While gold catalyzes the dehydrogenation of ethanol to form carbon–carbon triple bonds, the structure of ethanol utilizes the C2 carbon chain as a building block of the carbyne chain

• and the hydroxyl group forms the initial Au–H adduct needed for the catalytic reaction. Other alcohols, such as methanol or propanol, did not lead to carbyne formation during the experiments [139]. Condorelli et al. were able to synthesize carbon-encapsulated Pt nanoparticles by RLAL of graphite in a

• . Whereas the debate about the stability of the corresponding bulk phase carbyne continues until today, the existence of isolated chains of carbon atoms has meanwhile been corroborated experimentally. Since graphene, as the two-dimensional sp2-bonded allotrope of carbon, has become a vast field, the

The hybridizations, sp1, sp2, and sp3, correspond to bonding geometries in one-, two-, and three-dimensional space

The first papers claiming observations of sp-hybridized carbon as a new allotrope (named carbyne, and the mineral form was called chaoite) date back to the sixties by Kudryavtsev and co-workers [14], by El Goresy and Donnay [15] and by Whittaker
