Composition-dependent surface chemistry of colloidal BaxSr1−xTiO3 perovskite nanocrystals

Abstract

BaxSr1−xTiO3 perovskite nanocrystals, prepared by the vapor diffusion sol–gel method and characterized by state of the art surface techniques, display significantly different O–H stretching frequencies and adsorption properties towards CO2 as a function of the alkaline earth composition (Ba vs. Sr). The difference of properties can be associated with the more basic nature of BaO-rich than SrO-rich surfaces.
