摘要
The mechanisms of dissociation of oxygen-containing moieties (-OH, -HCO, -COOH) upon the photoreduction of graphite oxide by UV light have been considered. It has been concluded that the photoreduction, which involves the detachment of the OH group and the molecular elimination of CO and CO2, occurs in singlet excited states. The energy threshold of the photoreduction processes is determined by the position of the repulsive terms of the system.
