Abstract
In recent years, the photocatalytic properties of TiO 2 have been extensively studied. The anatase crystal structure of TiO 2 has a high reduction power and high photocatalytic activity. In present study, boric acid-based titanium dioxide and non-doped titanium dioxide have been produced by the two different methods and different sintering temperatures. Structural analysis indicated that boron-based samples resulted in spread homogeneously as in anatase crystal structure. Samples compared in different parameters were subjected to X-ray diffraction, Scanning Electron Microscope, Fourier-transform infrared spectroscopy, and moisture holding capacity measurements. XRD analysis of TiO 2 samples produced at 450°C, 600°C, and 750°C sintering temperatures was carried out to determine and compare crystal structures. The boron additive has been shown to maintain anatase crystal structure at high temperatures. The highest XRD score of anatase phase values were achieved as 73 and 78 at 750°C. These results were observed in boron-based samples. When the moisture holding capacity was examined, boric acid contribution has been seen to increase this capacity. The results demonstrated that these boron-based titanium dioxides with maintain anatase crystal structure in high temperatures, and promise moisture-holding capacity are prominent candidates for smart materials.
