Graphite reaction
WebIn case of graphite, the sp2 hybridized graphene layers are linked by rather weak van der Waals forces and π–π interactions of the delocalized electron orbitals.33 These layers can be stacked either in the thermodynamically more stable ABAB sequence with hexagonal symmetry or in the less stable ABCABC sequence with rhombohedral symmetry.34–36 … WebDetailed reaction rate models have been developed to analyze graphite oxidation. These models tend to show that graphite oxidation in N Reactor would be limited both by available oxygen and the requirement that a high-temperature source (>1100°C) be available to drive a significant reaction.
