The Surface Chemistry and Catalysis Group at Oak Ridge National Laboratory conducts research into surface chemistry and fundamentals of catalytic reactions at metal surfaces, metal oxide surfaces and supported metal catalysts. Two approaches include "surface science" studies of model surfaces and a "catalytic" studies of high surface area, novel materials.Research is also ongoing in chemical sensors using ion mobility and differential ionmobility mass spectrometry as chemical sensors and Nanowirestructuresfor LEDs and g-ray detection. A major portion of the group's effort is involved in the Catalytic Nanomaterials sub-task at the Center for Nanophase Materials Sciences (CNMS). Major portions of the group's basic research are sponsored by the DOE's Chemical Sciences Division of Basic Energy Sciences and the DOE's Scientific User Facilities Division within the Office of Basic Energy Sciences. Other sponsors include DOE's Office of Fossil Energy, SERDP and NA-22 programs, and private sponsors such as Eastman Chemical.
Research areas include: the surface chemistry of reducible oxide surfaces, the effects of oxide reducibility upon surface chemistry on model oxide surfaces and on supported metal particles, adsorption states and evolution of small molecules on oxide and metal surfaces probed both experimentally and using computer modeling (DFT), catalysis by supported Au and Rh surfaces; structure function relationships in Au catalysts, oxidation reactions, effects of nano-structuring and functional modification of supports upon surface chemistry and catalytic reactions; CO hydrogenation reactions for selective formation of ethanol.
