Rationally fabricating hollow particles of complex oxides by a templateless hydrothermal route: the case of single-crystalline SrHfO3 hollow cuboidal nanoshells
Abstract
Based on the theory of sol–gel science, perovskite SrHfO3 hollow cuboidal particles with tunable sizes were rationally synthesized by templateless hydrothermal reactions in KOH solutions. The concentrated KOH solution not only elevated the supersaturation of the reactants to promote the grain growth of SrHfO3 but also controlled the aggregated particle sizes by compressing the electrical double layers of the primary particulates. The following
