20.500.12556/RUL-136603 Synthesis of nanostructured TiO$_2$ microparticles with high surface area Hydrothermal reactions represent a simple and efficient method for the preparation of nanostructured TiO$_2$ particles that could be of interest as photocatalysts or catalytic supports. Although the particle size is in the range of 2–5 µm, the nanostructures composing the particles ensure a large specific surface area with values above 100 m$^2$/g. The effects of the different synthesis parameters on the morphology, photocatalytic activity, and stability of the prepared material were studied. The surface morphology of the prepared TiO$_2$ powders was studied by scanning electron microscopy (SEM). To further characterize the samples, the specific surface area for different morphologies was measured and the photocatalytic activity of the prepared powders was tested by degrading model pollutants under UV irradiation. The results show that the initial morphology had little effect on the photocatalytic properties. On the other hand, the final calcination temperature significantly increased the degradation rates, making it comparable to that of P25 TiO$_2$ (particle size 20–30 nm). titanium dioxide TiO$_2$ high surface area photocatalysis nanostructured particles titanov dioksid velika specifična površina fotokataliza nanodelci true false true Angleški jezik Slovenski jezik Članek v reviji 2022-05-12 12:16:51 2022-05-12 12:16:52 2022-09-15 04:14:03 0000-00-00 00:00:00 2021 0 0 11 str. iss. 12, art. 1512 Vol. 11 Dec. 2021 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 620.3:546.82-31 2073-4344 10.3390/catal11121512 101815299 catalysts-11-01512.pdf catalysts-11-01512.pdf 1 DB4576C620E800A5AA2DCCB8A0DFDB29 dab3f9439ad5267fd8f584e0d41036aeb268550e483db8f7ca57c67101738013 fd8c420c-d1dc-11ec-8aca-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=156317 https://www.mdpi.com/2073-4344/11/12/1512 1 88d7881e-d1dc-11ec-8aca-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=156316 Fakulteta za kemijo in kemijsko tehnologijo 0 0 0
