Email: firstname.lastname@example.org Abstract Titania (TiO2) nanoparticles (NPs) were prepared by wet chemical method by using 2-propanol, titanium isopropoxide as precursors and graphene were prepared from graphite by electro deposition method. The composision of two precusors and make a nanocomposite of TiO2/graphene using wet chemical method. The crystalline structures of prepared TiO2 /graphene NPs were revealed using Xray diffraction (XRD). The stretching and bending nature of synthesised NPs were explored using Fourier transform infrared spectroscopy (FTIR). Scanning Electron Microscopy (SEM) and Transmission Electron Microscopy (TEM) studies were confirmed that the prepared NPs were spherical in shape with an average particle size range from 20-85 nm.
Electrical and mechanical properties, and high
surface area make graphene a novel substrate for
forming hybrid structures with a variety of
relate to TiO2.
Graphene hybrids with metal oxides (TiO2) have
attributed to the O–H stretching vibrations of

XRD Characretisation The structure of the crystal is anatase phase for TiO2 NPs and hybrid of graphene presented in the
peak position of 25.37(highest), 54.31(lowest). JCPDS card No. 21-1272.
The average size of the crystalline size is 7nm. Fig 3: XRD patterns for TiO2/Graphene NPs

Conclusion A simple wet chemical method was used to prepare TiO2/Graphene NPs with the spherical morphology with small agglomeration. The characterisation of TiO2/Graphene NPs were studied by FTIR, XRD and SEM and TEM. XRD results show that the crystalline size is 7nm. The study of TiO 2/Graphene NPs on UV shielding.
