*3.2.4 Aliphatic compounds*

To decompose aliphatic precursors, high temperatures are needed to promote the partial or total dehydrogenation of carbon compounds, as well as the removal of other elements that could be previously linked to the chains, such as nitrogen and oxygen. Subsequently, it is necessary to promote the breaking of the carbon-carbon bonds between the chains. This favors the deposition of active carbon species on the metal substrate, the subsequent formation of graphene growth nuclei in sp2 formation, and the capture of active carbon for the growth of the graphene islands [15].
