Understanding the Role of Surface Metal-Oxygen Structures of Nanoalloys in Catalytic Reactions
EMSL Project ID
46204
Abstract
This proposal focuses on investigating a critical hypothesis that the surface metal-oxygen structures play an essential role in the catalytic activity of nanoalloy catalysts for reactions involving molecular oxygen species (e.g., CO oxidation and other oxidation or reduction reactions) and such structures can be manipulated at the atomic scale by processing temperature and atmosphere. The proposed project will develop an effective strategy to manipulate the surface metal-oxygen structures and establish their correlation with the activity for the catalytic reactions. To this end, the PI seeks to use the advanced x-ray photoelectron spectroscopic (XPS) and high-resolution transmission electron microscopic (HRTEM) techniques at the Environmental Molecular Sciences Laboratory User Facility for surface characterizations of the nanoalloy catalysts prepared in the PI's laboratory. This effort is part of the PI current research projects funded by NSF and DOE. The requested use of EMSL's facilities such as XPS and HRTEM will enable us in gaining a detailed understanding of the nanoscale surface structures of the nanoalloys which are fundamental for catalytic oxidation and reduction reactions.
