Oriented and ordered mesoporous ZrO2/TiO2 fibers with well-organized linear and spring structure

• The ZrO2/TiO2 fibers were prepared by EISA process combined with steam heat-treatment.
• The mesoporous ZrO2/TiO2 fibers have well-organized linear and spring structure.
• The fibers were composed of oval rod nanocrystals of ZrTiO4.

The ultra-stable order mesoporous ZrO2/TiO2 fibers with well-organized linear and spring structure and large surface areas under higher temperatures were prepared by a (simple evaporation-induced assembly) EISA process. The preparation, microstructures and formation processes were characterized by Fourier transformation infrared (FTIR), X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and N2 adsorption–absorption measurements. The fibers take on pinstripe configuration which is very orderly along or perpendicular to the axial direction of the fibers. The diameters of the pinstripe are in the region of 200–400 nm and arranges regularly, which are composed of oval rod nanocrystals of ZrTiO4.
