摘要：

The range of action of electronegative catalyst poisons on transition metal surfaces is of much current interest. Density of states calculations have been performed on small clusters to estimate the range of sulphur, phosphorous and carbon poisoning on the Ni(100) surface. Both sulphur and phosphorus poison nearest and next-nearest CO adsorption sites, and therefore have a range of operation of less than 5 Angstrom. Carbon poisons only nearest neighbour sites. The results of the calculations are compared with experimental measurements of D. W. Goodman.
