【 摘 要 】

Advancedindustrialized nations have experienced severe pollution problems over the pastforty years, caused mainly by carbon monoxide, hydrocarbons and nitrogen oxideemissions from automobiles. Catalyst technology has played a major part in minimizingthese emissions as required by even more restrictive laws. The catalyst hasbeen optimized over the years to meet the requirements of high activity andlong life. The oxidation of hydrocarbon and carbon monoxide are in advanceddevelopment stage while that of NOx catalysts is far less advanced.In the future, catalyst technology is expected to contribute to overcome thechallenges to get a cleaner air.
