Reticulated open-cell mullite (ROM) foams coated with graphene oxide (GO) multilayers as novel and reusable composites (ROM/GO) were first fabricated and functionalized to remove methylene blue (MB) dye from aqueous solutions. In this study, the ROM foams were produced via a replica technique utilizing rice husk as a starting raw material of silica (SiO) mixed with commercially available alumina (AlO) in the step of slurry preparation. GO was synthesized by a modification of Hummer's method and dispersed in a fixed weight ratio in an aqueous solution.

- Graphene oxide was synthesized from rice husk using a modified Hummers' method, with ground pencil leads as a control to ensure method consistency.
- TiO microspheres were created using a precipitation method with pluronic F127 as a template, and GO derived from rice husk was combined with these microspheres to form composites in different weight ratios.
- The composites showed high removal efficiencies (99-100%) for cationic dye methylene blue under UV light, outperforming GO and TiO individually, and can be reused multiple times due to their effective adsorption and photodegradation capabilities.
