Surface segregation electronic mechanism

The growth mechanism appears to be the same, irrespective of the hydrocarbon. However, the resulting morphology depends not only on the metal and particle size but also on the type of hydrocarbon and the reaction temperature. The importance of step sites on the catalyst surface for the nudeation of carbon was recently confirmed by in situ investigations employing high resolution transmission electron microscopy the results indicate the segregation of carbon when the formation of whiskers takes place at specific sites on the nickel surface. The addition of potassium to the nickel catalyst leads to an increase in the induction period (t ) for CH4 decomposition, which... [Pg.306]
