A facile effective one-step low-temperature hydrothermal approach was employed to in situ embed ZnO nanorods into the porous cellulose aerogels. Besides, the preparation of cellulose aerogels is based on a green NaOH/polyethylene glycol solution. The rod-like ZnO has average diameter of about 348 nm and length of about 1.49 mu m, and displays wurtzite phase. Meanwhile, the scanning electron microscope and transmission electron microscopy observations confirm that the nanorods are tightly anchored to the aerogels matrixes, and exhibit good dispersion without dramatic agglomeration, indicating that the cellulose aerogels are a class of ideal green matrix materials to support nanoparticles. Moreover, the method might also be extended to fabricate other multifunctional cellulose-based nanocomposites.
