WebFeb 24, 2024 · The graphene papers with boron catalyst annealed at 2,000 °C show a high conductivity of ∼ 3,400 S·cm −1, about 47% higher than pure graphene papers. Boron catalyst facilitates the recovery of structural defects and improves the degree of graphitization by 80%. WebOne option that is being increasingly explored is the process of iron-catalyzed graphitization. This simply involves the pyrolysis of carbon-rich precursors in the presence of an iron catalyst and has been used to produce carbons with a wide range of structures and properties. This review will examine the current field of iron-catalyzed ...
