摘要

TiO2 nanoparticles (10-20 nm) are often used as electrode materials for dye-sensitized solar cells. With multi-TiO2 particles-based nanofluids, we have investigated the effects of sintering parameters such as ramping rate, maximum temperature and period of maximum temperature on fusing nanoparticles and porosity. Rutile-phase rod-shaped TiO2 nanoparticles having high surface area (201 m2/g) were synthesized at 27 °C using TiCl4 in aqueous solution with non-hydrothermal method. The water-based nanofluid consisting of the Rutile rod-TiO2 and spherical Anatase TiO2 nanoparticles was deposited on conductive FTO glasses by spin-coating method, and subsequently it was sintered, while systematically changing the ramping rate, maximum temperature and time of maximum temperature, using a programable oven. SEM measurements without and with different sintering strategies were captured to observe the effects of sintering parameters.
