“…The slight weight loss before 120 C is ascribed to the evaporation of adsorbed water molecules. As the complete decomposition temperature of graphene has been generally considered to be around 700 C, [47][48][49][50] the weight loss at this temperature has been assumed to correspond to the content of MLG in the TiO 2 /MLG composite, which is estimated to be 5.8%. In addition, the wide exothermic peaks of TiO 2 /MLG reects the oxidization of the carbon skeleton of MLG, which can be affected by the formed C-Ti bond and the distribution of TiO 2 creating localized spots to facilitate the oxidization reaction.…”
