Morpho-structural characterization of Ti[O.sub.2] nanosized powders with photocatalytic potential

Anatase/rutile mixed nanopowders were obtained by laser pyrolysis technique and the influence of the flow rate of the oxidizing agent on their morpho-structural properties was explored by transmission electron microscopy (TEM), X-ray diffraction (XRD) and Raman spectroscopy.

Zusammenfassung:Anatase/rutile mixed nanopowders were obtained by laser pyrolysis technique and the influence of the flow rate of the oxidizing agent on their morpho-structural properties was explored by transmission electron microscopy (TEM), X-ray diffraction (XRD) and Raman spectroscopy. The revealed particularities were comparatively discussed with those of the commercial product Degussa P-25 from the perspective of the photocatalytic performances. Keywords: Ti[O.sub.2] nanosized powders, morphological investigations, structural properties
