(a) Apart from Sb 0% all the Sb : SnO2 particles are blue powders.
(b) Present in the bulk and at the surface; at the surface as NH3 groups.
(c) The diameter is calculated assuming that the particles were spherical, non-porous with a density of 6.99 g/cm3.
(d) The particles are (almost) crystalline. The crystallite sizes were calculated from the broadening of the XRD peaks.
(e) No Sb(III) was detected with XPS; IR data suggest that a very small amount of Sb(III)-OH surface groups is present.
(f) Measured with TEM: d = 6.3 ± 1.1 nm.
