| description | A series of pure ZnO and graphene doped ZnO nanohybrid samples were synthesized
via ultrasonic assisted sol-gel method using reducing agent Hexamethylenetetramine
(HMTA) at different weight percentage. The prepared sample were characterized by
XRD, FTIR and UV-Visible to study the structural, functional and optical properties.
XRD analysis reveals that as pure ZnO, all the diffractive peaks can be indexed as the
hexagonal ZnO while for ZnO/Graphene nanohybrids shows a diffraction peaks at
28 (002) = 26.42 indicating the graphene has been successfully doped. The estimated
crystallite size was decreased as increased the Graphene weight % in the range of
32.94 - 40.32 nm. In UV-Vis spectra, two absorption band were observe that can be
assigned to absorption of ZnO crystal with correspond absorption edge at 375 nm
and the peak at about 302 nm is describe to graphene absorption. The FTIR analysis
demonstrate that the functional group present in the obtained product. The
ZnO/Graphene nanohybrid may be ideal candidates for photocatalyst application |
