Abstract

We have carried out studies of hydrogen adsorption on sulfur covered Ru(001) and observed two weak hydrogen adsorption states with desorption temperatures at 135 K and 265 K. The existence of these hydrogen states is attributed to the long-range electronic effects of sulfur adatoms in addition to their site blocking, and also to the repulsive interactions among coadsorbed hydrogen within a p(2×2)-S structure.
