3D structure aerogels constructed by reduced graphene oxide and hollow TiO2 spheres for efficient visible-light-driven photoreduction of U(vi) in air-equilibrated wastewater

A novel 3D structure composite aerogel was constructed by nanostructured hollow TiO₂ and RGO with excellent photocatalytic reduction activity for U(vi) and reusability, evidencing the potential practical applications in environmental remediation.
