Figure 8: Schematic flowchart of in situ incorporation of GS in nanostructured TiO2 films. (a) GS prepared by chemical exfoliation with residual oxygen-containing functional groups, such as hydroxyl. (b) Schematic of titanium(IV) butoxide grafted on the reduced GS surfaces by chemisorption. (c) Schematic diagram of GS coated with TiO2 colloids after hydrolysis. (d) Illustration of the electrophoretic deposition process used to prepare GS/TiO2 composite films. (e) Schematic representation of the structure of the GS/TiO2 composite film after calcination [147].
