Low-coordinated sites are surface defects whose presence can transform a surface of inert or noble metal such as Au into an active catalyst. Starting with a well-ordered Au(111) surface we prepared by ion sputtering gold surfaces modified by pits, us

Mixed-metal oxides exhibit novel properties that are not present in their isolated constituent metal oxides and play a significant role in heterogeneous catalysis. In this study, a titanium-copper mixed-oxide (TiCuO x ) film has been synthesized on C

Adsorbate-driven morphological changes of pitted-Cu(111) surfaces have been investigated following the adsorption and desorption of CO and H. The morphology of the pitted-Cu(111) surfaces, prepared by Ar(+) sputtering, exposed a few atomic layers dee

Previous work has shown that CO{sub 2} adsorption on bulk potassium leads to the formation of oxalate ions below room temperature. These C{sub 2}O{sub 4} groups decompose in vacuo to carbonates, CO{sub 3}, and CO around 300 K and the carbonates furth
