Facile preparation and characterization of anatase TiO2/nanocellulose composite for photocatalytic degradation of methyl orange

Anatase TiO2/nanocellulose composite was prepared for the first time via a one-step method at a relatively low temperature by using cellulose nanofibers as carrier and tetrabutyl titanate as titanium precursor. The morphology, structure and element composition of the composite were characterized by...
