Cellulose is a kind of renewable biological template with complex microstructure. Surface sol-gel technology, a practical and environmental-friendly approach to produce silica nanotubes, was discussed in this paper. A series of characterization techniques, namely thermal field emission scanning electron microscopy (SEM), and Aztec X-act spectrometer were used to characterize these samples. The design of the nanotube structure was achieved by natural cellulose and cellulose nanocrystals (CNC), and this nanocopying methodology provided silica nanotubes of cellulose template in nanometer precision.
