Ključnе rеči: | Nanopowder TiO2 Sol–gel synthesis Raman spectroscopy Photocatalysis | Dаtum izdаvаnjа: | 2012 | Čаsоpis: | Journal of Sol-gel Science and Technology | Sažetak: | Nanocrystalline titanium dioxide (TiO2) powders have been synthesized by sol–gel method using titanium tetrachloride (TiCl4) or tetrabutyl titanate (Ti(OC4H9)4 as precursors, different alcohols and calcination temperatures in the range from 400 to 650 C. The photocatalytic activity of asprepared powders has been tested for the degradation of metoprolol tartrate salt, a selective b-blocker used to treat a variety of cardiovascular diseases, and compared to photocatalytic activity obtained fromDegussa P25.Nanosized TiO2 powders prepared from TiCl4 and amyl-alcohol, calcined at 550 C, displayed an activity comparable to Degussa P25, whereas the sample from the same series, calcined at 650 C, showed higher photocatalytic activity in the whole range of the catalyst loading. Structural, morphological and surface properties of synthesized TiO2 nanopowders have been investigated by XRD, SEM, EDS and BET measurements, as well as FTIR and Raman spectroscopy, in order to find out the material properties which enable rapid an efficient decomposition of metoprolol under UV radiation. | URI: | https://open.uns.ac.rs/handle/123456789/24599 | ISSN: | 0928-0707 |
