Novel Pd-based Three-Way Catalysts

摘要

Three-way catalyst development programs focusing on processing precious metals on washcoats and on the application of the precious metals on certain washcoat components were initiated with the goal of improving the performance of three-way catalysts so as to fulfill the planned future emission standards with reduced precious metal costs. The different programs included newly developed Pd-only and Pd/Rh catalysts and novel oxygen storage components.
