Abstract
We report experimental results on the interaction of hydrogen with monolayer thin Ag and Au films grown on a Pt(1 1 1) substrate, measured with thermal desorption spectroscopy (TDS) and nuclear reaction analysis (NRA). We found that H2 dissociative adsorption is activated on both thin film surfaces. Atomic hydrogen was found to adsorb on the Ag and Au films on Pt(1 1 1) with main desorption temperatures of 160 and 120 K, respectively. The monolayer thin Ag and Au films on Pt(1 1 1) are chemically similar to the (1 1 1) surfaces of bulk Ag and Au, respectively.
