12 Future Automotive Catalysis

Sunday, November 16, 2014: 3:30 PM
308 (Hilton Atlanta)
Description:
The three-way automotive catalyst technology has been one of the greatest successes in heterogeneous catalysis over the last 35 years. However, there is a recognized need for big steps in catalyst development paring with advanced combustion technologies that have offered significant improvement in fuel economy and lowering greenhouse gas emissions. This session focuses on future automotive catalysis for lean NOx emission as well as low-temperature hydrocarbon controls. Contributions of this session will include expertise in automotive exhaust catalysis, computational catalysis, and catalyst characterization. The outcome will simultaneously advance both the science of a novel class of catalysts and their engineering for timely and critical energy- and environment-related applications.
