Activities during this report period focused on testing of additional modified and promoted catalysts and characterization of these materials. Methanol oxidation studies were performed as a method of acid site characterization. Improvements to the product gas analysis system continued to be developed. These results are reported. Specific accomplishments include: (1) Obtaining and interpreting infrared spectra of modified catalysts prepared to enhance surface acidity. (2) Testing of these catalysts in methanol oxidation as a method of acid site characterization and to determine catalytic activity for conversion of this desired product. Catalysts were quite active for methanol conversion to dimethyl ether. Two of the modified catalysts prepared in this work exhibited the highest activity for this reaction, presumably because of their higher surface areas. (3) Determination that acidity modifications had no effect on activity for methane conversion
