IGR NO{sub x}/SO{sub x} control technology. Quarterly report January 1, 1995--February 28, 1995

During the first quarter of 1994, work was concentrated on improving the power efficiency of the IGR NOx/SOx control technology. IGR continued to work on its electrocatalyst materials to improve the electrical efficiency required for economical NOx/SOx destruction. In addition IGR continued to modify the electrocatalyst/electrolyte interface with the goal of improving selectivity and current efficiency. Specifically, work concentrated on changing the solid state defect concentration in the solid oxide electrolyte both on the surface and in the bulk. Results from two months of work indicate that these modifications have significantly improved current efficiency. For some conditions the current efficiency was improved by a factor of ten. Further work has been truncated as we have reached the end of the Phase I term of this research contract
