<P><B>Abstract</B></P> <P>Hybrid 3-dimensional (3D) structures composed of zinc oxide (ZnO) nanorods and reduced graphene oxide hydrogel (rGOH) were fabricated by chemical reaction between Zn ions and GO followed by <I>in-situ</I> lateral growth of ZnO nanorods using Zn ions as seed points. The 3D networked ZnO nanorod–rGOH (ZNR–rGOH) fabricated in this study exhibited excellent methylene blue (MB) removal efficiency due to efficient physical adsorption of dye molecules because of electrostatic attractive forces and enhanced photocatalytic activity by the laterally grown ZnO nanorods. The Langmuir–Hinshelwood rate constant of ZNR–rGOH was 4-fold higher than that of pristine rGO due to the enhanced photocatalytic effects obtained by incorporating laterally grown ZnO nanorods inside the rGOH network.</P> <P><B>Highlights</B></P> <P> <UL> <LI> The Covalently-bonded 3D networked graphene hydrogel was fabricated using Zn ions. </LI> <LI> ZnO nanorods were laterally grown inside rGOH networks using hydrothermal synthesis. </LI> <LI> Dye removal efficiency was highly enhanced by using hybrid structures. </LI> <LI> Visible light photocatalytic activity was also observed in the hybrid structures. </LI> </UL> </P> <P><B>Graphical abstract</B></P> <P>[DISPLAY OMISSION]</P>
