Figure S1. Transmission (TEM) and scanning (SEM) electron microscopic images showing the
microstructure of titania prepared by thermal decomposition of the precursors. (a) acetylacetonate
precursor, 673 K (TEM); (b) lactate precursor 673 K (TEM); (c) acetylacetonate precursor, 873 K (SEM);
(d) lactate precursor, 873 K (SEM); (e) acetylacetonate precursor, 1473 K (SEM); (f) lactate precursor,
1473 K (SEM). Scale bars correspond to 100 nm (a, b), 400nm (c, d), and 1 m (e, f), respectively.
Figure S2. X-ray diffraction patterns of materials prepared by thermal decomposition in oxygen of the Vdoped acetylacetonate-containing precursor. The temperatures of the thermal treatment range from 673 to
1273 K, in 100 K intervals (from bottom to top). Reflections marked with A and R correspond to the
anatase and rutile TiO2 phases, respectively.

decomposition in oxygen of the acetylacetonate-containing precursor .The temperatures of the thermal
treatment range from 673 to 1473 K, in 100 K intervals (from bottom to top). Reflections marked with A,
R and RS correspond to the anatase, rutile and rock-salt phases, respectively.
