Influence of surface defects and local structure on oxygenate reaction pathways over metal oxide surfaces. Progress report, August 1992--July 1993 (open access)

Influence of surface defects and local structure on oxygenate reaction pathways over metal oxide surfaces. Progress report, August 1992--July 1993

Complete thermal desorption and photoemission studies of seven molecules (methanol, formaldehyde, formic acid, isopropanol, acetone, waste and carbon monoxide) have been completed on four different SnO{sub 2}(110) surfaces (stoichiometric, reduced, slightly-defective and highly-defective). Initial thermal desorption studies of acetic acid and propene have also been done. Results indicate that different initial surface conditions can dramatically affect: (1) probability for heterolytic dissociation of Bronsted acids, (2) reaction kinetics for unimolecular decomposition of oxygenated surface intermediates, and (3) product selectivity.
