Abstract
Possible future developments of new automobile catalysts undoubtedly u tilize transient phenomena at the change of gas composition under the cooperative functions of the catalytic components: noble metal particl es, supports and third additives including 'migration' of adsorbed spe cies and their temporal 'storage'. To explore highly cooperative he ts of the catalytic components, a new tool to detect transient products from artificially designed small area samples in the ms range was deve loped, which is more robust and tolerant for dynamic changes of vacuum conditions than the conventional UHV surface science tools.
