Preparation and characterization of regenerated cellulose/TiO2/ZnO nanocomposites and its photocatalytic activity

Abstract Regenerated cellulose (RC)/TiO 2 /ZnO nanocomposites have been prepared via hydrothermally grown ZnO on the RC/TiO 2 nanofibers. The RC/TiO 2 nanofibers were prepared by electrospinning technology followed via sol–gel process. Results show that a plenty of amorphous TiO 2 sol particles is dispersed on the surfaces of the RC nanofibers, and ZnO (wurtzite structure) nanosheets could be fixed on the surface of RC/TiO 2 nanofibers. The photocatalytic activities indicate that the RC/TiO 2 /ZnO nanocomposites perform a higher photocatalytic property than RC/TiO 2 nanocomposites nanofibers or pure ZnO nanosheets.
