High Resolution Electron Microscopy Study of Nanostructured Materials
EMSL Project ID
25593
Abstract
The objective of this proposal is to use EMSLs advanced electron microscopy facility to characterize the compositions and properties of the nanostructured catalysts and nanostructured materials and correlate the structure-property relationships. In particular, we will use high resolution TEM to study the spatial distribution of the metal particles supported on nanocrystalline or porous supports, the nature of the interface between the supports and the active components, the nature of the surface and grain boundaries in well-defined nanocrystalline transition metal oxides we developed at PNNL, the nature of the microporous and mesoporous channels in new open structured metal oxides discovered at PNNL, and the nature of the defects in the bulk of new nanocrystalline materials. The high resolution TEM study is a critical component of two laboratory wide initiatives: The Catalysts Initiative and the Transformational Materials Initiative. The lab wide initiatives are the largest internal investments at PNNL aimed to establish transformational scientific capabilities to address long term DOE challenges in energy and environment. These initiatives cannot succeed without the high resolution TEM facilities which will provide critical information to guide materials development activities and help understand the fundamental structure and property relationships. In addition, the TEM study is also critical for two ongoing projects in related areas funded by BES: "Early Transition Metal Oxides as Catalysts" and "Nanostructured Catalysts for Hydrogen Generation."
