2.2. Synthesis of Nanocomposites
Figure 1 shows the specific process, rGO-TiO2nanomaterial was prepared by the reaction of graphene oxide and tetrabutyl titanate through a hot solvent (Karthikeyan & Prabhakaran, 2018; Karthikeyan et al., 2018b). The graphene oxide was poured into isopropanol and sonicated. Then add tetrabutyl titanate, stir well, and then add 1 mL of ultrapure water to the mixed solution. After stirring for 30 minutes, it was transferred to a polytetrafluoroethylene lining and reacted at 180 °C in a blast drying oven. After 8 hours of reaction, the precipitate was centrifuged and washed several times with absolute ethanol. After drying for several hours, a small amount of black product was obtained, which is the target product of this experiment.
