- The primary goal of the last year of the research program was to create a new type of selective heterogeneous catalyst. The new catalysts were synthesized, their unusual selectivity assessed by a model reaction, and some of the parameters which are important in creating unusual selectivity in these catalysts determined. Near the end of this proposal, considerable excitement was generated by the discovery of high temperature superconductors. It was decided to briefly investigate the activity of some superconductors and related cuprates. This research was done in concert with a project funded by Ford Motor Company. Catalysts were investigated for two reactions useful in pollution control: CO oxidation and NO reduction. In addition, some stoichiometric measurements of the oxygen content of superconductors and related cuprates were made using a TPR apparatus in the lab. In addition, some experiments were done with the objective of preparing novel MO-Pd/Al₂O₃ catalysts in which the Mo and Pd were in close contact. These catalysts have the potential of replacing much more expensive rhodium containing catalysts which are currently used for emissions control. Progress on the following is described: H₂-D₂ exchange on transition metals; New method of determining the number of active sites; New method of determining the hydroxyl content of catalysts; H₂-D₂ exchange on metal oxides; Reactive characterization and atomic isolation of active sites; Site isolated catalysts synthesized by selective poisoning; Catalysts prepared from high temperature superconductors; Mixed metal Pd-Mo catalysts; and Selective reduction of nitric oxide.
