【 摘 要 】

Advanced industrialized nations have experienced severe pollution problems over the past forty years, caused mainly by carbon monoxide, hydrocarbons and nitrogen oxide emissions from automobiles. Catalyst technology has played a major part in minimizing these emissions as required by even more restrictive laws. The catalyst has been optimized over the years to meet the requirements of high activity and long life. The oxidation of hydrocarbon and carbon monoxide are in advanced development stage while that of NOx catalysts is far less advanced. In the future, catalyst technology is expected to contribute to overcome the challenges to get a cleaner air.
