Calculation of Chemisorption and Absorption Induced Surface Segregation
نویسنده
چکیده
Using a pair bond type model for the interatomic interactions. we determine surface scgregation on clean, H, 0 and CO covered surfaces of various alloys. Furthermore, we study surface segregation caused by bulk hydrogen absorption. Numerical results are presented for Pd ,Zr, ~ H, We find, that strong surface segregation may result from chemisorption of 0 and CO and from absorption of H in the bulk of an alloy.

Adsorption of CO molecule on the Vanadium surface has been studied by using of the DFT method with LANL2DZ,6-31G* and 6-31G** basis sets by GGA approximation of theory. Using periodic first principles simulations we investigate the interaction of oxygen molecule with regular V (100) surface. The limitation of this approach is the use of thin metallic slabs with a limited range for their coverag...
متن کاملKINETICS OF HYDROGEN ABSORPTION BY CHEMICALLY MODIFIED Pd( 110) *
The kinetics of hydrogen absorption by Pd(ll0) have been measured as a function of impurity sulfur coverage on the metal surface. In contrast to results obtained on the clean surface in which the absorption process was found to be rate-limited by the diffusion of atomic hydrogen into the bulk, submonolayer coverages of sulfur cause the kinetics to become surface dominated with the dissociative ...
