Influence of Pressure to Morphology of TiO<sub>2</sub> Nanofibers Prepared by Microwave-Assisted Synthesis Method

Abstract

Microwave-assisted hydrothermal synthesis of TiO2 nanofibers under various temperature and pressure conditions were done in this research. High quality TiO2 nanofiber coatings where obtained when temperature was in range 240 – 245 °C and pressure was 27.3 – 29.1 bar. Obtained TiO2 nanofiber coatings are with a specific surface area of ​​151.5 to 158.9 m2· g-1 before calcination. Comparing with nanopowder photocatalysts nanofiber coatings photocatalysts can be much easier removed from solution after the photocatalysis process. Such coatings with relative large specific surface area are with higher potential application in industry.
