Characterization of carbon nanotube/titanium dioxide acid treatment nanocomposite structure using sol-gel method

Titanium dioxide had been noticed thoroughly for their superiorities over conventional p-n junction devices, such as low cost and slighter toxic in construction. In this research, we present and study the preparation of Carbon Nanotube/TiO₂ acid treatment nanocomposite by the alteration of acid-catalyzed sol-gel method. The CNT/TiO₂ nanocomposite powder was acid treatment in NaOH solution and directed on FTO glass substrates. The CNT/TiO₂ paste was doctor blade onto the substrate plate to form a 1.0 cm² active region and later on annealed at 550°C, 650°C and 750°C for 30 min. The characterization of the TiO₂ adhesive was carried out by X-ray diffraction (XRD) and the results indicate that the particles of CNT/TiO₂ are in rutile form not in anatase structure. The micrographs of scanning electron microscopy (SEM) images prove that the thin film pastes have high porosity and the Brunauer Emmett Teller (BET) result show the surface area, pore volume and pore size for the CNT/TiO₂ thin film.
