Abstract
Embodiments herein generally relate to a process for capture of carbon dioxide (CO2) and conversion to graphite or graphene. In at least one embodiment, the process comprises: capturing carbon dioxide (CO2) using calcium oxide (CaO) to produce calcium carbonate (CaCO3); recovering the carbon dioxide (CO2) from the calcium carbonate (CaCO3); and reacting the carbon dioxide (CO2) with an active metal to produce graphite (C).
