Surface energy effects on the stability of anatase and rutile nanocrystals: A predictive diagram for Nb2O5-doped-TiO2

[Display omitted] •Anatase-rutile phase transition diagram was built for nano Nb2O5-doped-TiO2.•Nb2O5-doping postpones the anatase-to-rutile transition.•The stability crossover for TiO2 was 17.3nm, for 2mol% Nb2O5-doped-TiO2 ∼30nm.•The surface energy for Nb2O5-doped-TiO2 decreases systematically wit...
