ECOLOGİCAL FEATURES OF THE PHOTOCHEMİCAL PROPERTİES OF TİO2 NANOPARTİCLES

TiO2 nanoparticles have recently been widely used in environmentally important reactions.TiO2 particles have been studied by XRD, TEM, SEM analysis. It has been determined that the size of nanoparticles is homogeneous and generally varies between 10-30 nm.The results were consistent with the calculations by the Sherrer method. The results of the SEM analysis were the same as the XRD analysis.In the XRD spectra of TiO2 nanoparticles, the points at all peaks were accurately checked and the TiO2 nanoparticles matched the rutile phase.According to the Scherrer method, the average size of TiO2 according to the diffraction point (101) was 10.3, the specific surface area of the crystals was 159.6 m2/g.The signals for TiO2 nanoparticles had characteristic peaks at 27.90° (110), 36.01° (101), 41.58°(111), and 54.71°(211).
