AbstractThis study aimed to fabricate sand/zinc oxide (ZnO) nanorods (NRs)-based
nanocomposite via sol-gel immersion method with titanium dioxide (TiO2) and graphene oxide
(GO)-based materials for methylene blue (MB) dye degradation.The nanocomposite photocatalyst was
initially fabricated by growing ZnO via sol-gel immersion followed by synthesizing TiO2
using hydrothermal method on the sand as a substrate. Different concentration and synthesis time
were used as parameters for the fabrication. These nanocomposites were then hybridized with
GO and GO_multi- walled carbon nanotubes (MWCNTs) hybrid solution via immersion method. Prior to
hybridization, the initial GO was synthesized using electrochemical exfoliation method assisted by
commercially available single-tail sodium dodecyl sulphate surfactant and was further mixed with
MWCNTs to form GO_MWCNTs hybridsolution. The sand/Zn.....
