Synthesis of TiO2 and ZnO nano and submicrometric fibers by solution blow spinning.

Nano and submicrometric fibers of TiO 2 and ZnO were produced for the first time by solution blow spinning (SBS). High surface area, homogenous, crack free TiO 2 and ZnO fibers were successfully spun, as confirmed by BET surface area, X ray diffraction (XRD), transmission electron (TEM) and scanning electron (SEM) microscopy studies. TiO 2 and ZnO fibers presented mean diameters ranging from 300 nm to 600 nm and from 200 nm to 550 nm, respectively. SBS proved to be an efficient method of producing metal-oxide semiconductor nano and submicrometric fibers at high output rates when compared other fiber spinning techniques. [ABSTRACT FROM AUTHOR]
