Abstract

Carbon-based structures characterized by a polygonal cell distribution are commonly named random networks. On the other hand, well defined, molecular and therefore nanometric networks such as fullerenes, nanotubes and graphene have been some of the most remarkable discoveries in the area of carbon research in recent years. Another ill-defined type of randomly carbon network is that corresponding to the microporous structure of activated carbons (AC). So, three carbonaceous network structures can be considered according to the dimension: the molecular (fullerenes, nanotubes, graphene), the micro (microporous carbon), and the macro (macroporous carbon). Although in the case of carbon materials, synthetic routes for both molecular-networks and micro-networks have been extensively investigated, few studies exist regarding the synthesis and characterization of random networks of carbon. This work presents the synthesis and characterization of 2D and 3D polygonal random networks of carbon (RNC) from the controlled pyrolysis of saccharose in absence or presence of KOH.
