Bifunctional regenerated cellulose membrane containing TiO2 nanoparticles for absorption and photocatalytic decomposition

A simple and green method was presented to embed TiO2 on regenerated cellulose membranes via cellulose dissolution-regeneration process. The physical, chemical and mechanical properties of the composite membranes were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), Four...
