Abstract

In this study, nanometric measurement of the TiO₂ powders were analysed that were synthesized via flame spray pyrolysis for photocatalytic decomposition process. Continues increase of new metrological demands have enabled to fulfill the highest demand in measurement resolution. In order to obtain crystalline structure, the produced powders were post-annealed at 600oC after flame spray pyrolysis process. The phase structure was analyzed by x-ray diffractometer (XRD). Particle size of the powders was determined using particle size analyzer. The morphology and accurate size of the primary particles were further investigated by several devices in order to illuminate the particle size, phase structure, morphology and photocatalytic properties
