Titanium dioxide nanorods in regenerated cellulose membrane for photocatalytic degradation of phenol

Polymer-inorganic nanocomposite membrane was successfully prepared via incorporation of nitrogen doped (N-doped) titanium dixide (TiO2) anatase/rutile mixed phase nanorods in the cellulose microfiber by using phase inversion technique. The use of the non-toxic solvent-based system and recycled newsp...
