Abstract

Abstract : Synthetic protocols to generate well-integrated frameworks of known composition are important for the rational design of advanced materials. Abstract : Synthetic protocols to generate well-integrated frameworks of known composition are important for the rational design of advanced materials. 3D CeO2 /NiO hierarchical assemblies were designed and constructed with 2D CeO2 /NiO heterostructures as building blocks consisting of NiO nanosheets wrapped with CeO2 ultrathin nanosheets on the surfaces. The growth process of the 2D CeO2 /NiO heterostructure nanosheets and the 3D assemblies was described based on a domain-matching growth process. The CeO2 /NiO assemblies exhibited superior catalytic properties for CO oxidation. A model of the structure–property relationships based on surface and interface structures is discussed.
