The powder samples of TiO2 and TiO2/Graphene were prepared
by drying at 500 _C in a heating furnace. Fig. 6 shows the comparison
of XRD patterns of pure TiO2 and different concentration of
graphene in TiO2. The anatase structure is confirmed by the
diffraction peaks of (101), (211), (200), (105), and (004). A sharp
peak at 2q ผ 25.0_ can be attributed to anatase TiO2 according to
the standard pattern of anatase TiO2 (JCPDS 21-1272).
