Organic and Inorganic Template-Assisted Synthesis of Silica Nanotubes and Evaluation of Their Properties.

Mesoporous silica network nanotubes were fabricated using both organic and inorganic templates such as citric acid (CA), cetyltrimethylammonium bromide (CTAB), and sodium bicarbonate (SBC). The phase analysis of synthesized silica network was confirmed by X-ray diffractometer (XRD) analysis, and the present functional groups were revealed by Fourier Transform Infrared Spectroscopy (FTIR) and the formation of tubular morphology was analyzed by transmission electron microscopy (TEM). The mesoporous nature of each template sample was studied using Brunauer-Emmett-Teller (BET) instrument. The surface area and porous size were calculated successfully for fabricated silica network nanotubes.
