Surface modification of Nb-doped TiO2
nanoparticles by AcAc ligand
ensures thermodynamic stabilization between nanoparticles, thus the
precipitated product can be redispersed in alcohol solvent by gentle agitation and heating (~60 °C) with up to 30 wt.% solid content [24].
Three different nanoparticle samples were prepared with respective
Nb doping ratio of 0, 3, and 6 mol%. Heavier doping of Nb more than
10 mol% was also carried out, which appeared to be unsuccessful due
to a relatively poor dispersibility in organic solvent. Since the
