Note générale:Most of the catalysts used in industry or in automotive pollution control are conditioned as a dispersion of small catalytic particles on a support of high specific area. Assuming a similar bulk composition, the extremity of a sharp metallic tip can mimic one of these catalytic particles. Field ion microscopy (FIM) is used to characterise these surfaces at the atomic scale at cryogenic temperatures and subsequently to image catalytic surface reactions at temperatures where they usually occur.
