• Cellulose carbon aerogel
• Photocatalytic
• Adsorption heavy metal ions

A novel functional cellulose carbon aerogel@Na2Ti3O7@Cu2O (CA@Na2Ti3O7@Cu2O) nanocomposite was prepared by in situ growth technique and impregnation method, and its photocatalytic and adsorption properties were explored. The cationic intercalation structure of Na2Ti3O7 nanosheets gives CA@Na2Ti3O7@Cu2O nanocomposites excellent adsorption capacity of heavy metal ions (31.0-118.7 mg/g). The Cu2O nanoparticles in CA@Na2Ti3O7@Cu2O nanocomposite showed excellent photocatalytic activity, and the removal rate of methylene blue (MB) was up to 99 %. Furthermore, the CA@Na2Ti3O7@Cu2O nanocomposites could be easily regenerated and reused, providing a new way to effectively solve the problem of wastewater treatment containing heavy metal ions and organic dyes.
