Influence of surface defects and local structure on oxygenate reaction pathways over metal oxide surfaces
Work during the first budget period has thus far concentrated on the surface chemistry of the CC{sub 1} oxygenates (methanol, formaldehyde, formic acid), and its dependence on surface defects and tin cation coordination numbers on the SnO{sub 2}(110) surface. During the remaining six months of the first budget period, these initial C{sub 1} studies will be completed and work will be initiated on understanding the scrambling of lattice oxygen into the oxidation products from the C{sub 1} molecules. This upcoming work will utilize the preferential labeling of bridging lattice oxygen positions on the SnO{sub 2}(110) surface with {sup 18}O (1) so that the specific crystallographic origin of the oxidizing atoms can be determined. 6 refs.
