This   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.....
