Simultaneous Sc-doping and suboxide transformation of anatase TiO2 nanoparticles
Original language description
Self-assembled agglomerates of 4 at.% Sc doped titania (4SDT) nanoparticles (NPs) were obtained using a simple water-based co-precipitation of titanium oxysulfate and scandium oxalate with urea at low temperature. Undoped samples were also prepared for comparison. Aberration-corrected scanning transmission electron microscopy and dual electron energy loss spectroscopy (DualEELS), showed that 4SDT agglomerates comprised self-assembled anatase NPs and sub-stoichiometric trititanium pentoxide (β-Ti3O5). The Ti3O5 either surrounded the anatase NPs as an ultra-thin outer layer or grew on the anatase surface in randomly distributed “nanoislands” closely connected to the Sc3+ ion. Heating to 800 °C under air caused the Sc3+ to segregate out the anatase lattice to form Sc-rich oxides (usually Sc4Ti3O12). Also, it was detected that the Ti4+ amount increased at the expense of Ti3+. X-ray photoelectron spectroscopy (XPS), employed to investigate the elements' surface composition, oxidation states, and electronic configurations, showed 4.6 % Sc relative to the sum of Sc and Ti, close to the nominal composition of 4 %. The O/Ti values found for 4SDT by XPS and EELS were 2.3 ± 0.1 and 2.2 ± 0.2, respectively.
