Difference in oxidative reactivity of polycyclic aromatic hydrocarbons with zigzag, armchair, and 5-7 ring edges

摘要

Oxidation of carbon materials influences endurance of carbon materials for most applications. Complete understanding of the mechanisms for oxidation reaction is urgent to increase longevity of carbon materials. Mechanisms of oxidation reactions have been reported experimentally and theoretically. Some studies have reported the difference of reactivity depending on edge states such as armchair and zigzag. However, there are still some unclarity of mechanisms for oxidation reaction. One of the approaches to solve this problem is to understand mechanisms of oxidation of polycyclic aromatic hydrocarbons (PAHs) completely. In this work, the difference in oxidative reactivity of polycyclic aromatic hydrocarbons (PAHs) containing armchair, zigzag, and 5-7 ring edges was investigated by heat treatment in oxygen gases.
