Systematic studies were carried out as a function of reaction temperature and CO+O(2) composition. With sufficient kinetic evidence, we have demonstrated the positive influence of subsurface oxygen towards CO-adsorption and oxidation to CO, at high temperatures (600-900 K) on Pd-surfaces, and the likely electronic nature of the surface changes with oxygen in the subsurface. These studies also provide a direct proof for CO-adsorption with a significantly reactive sticking coefficient at high temperatures on Pd-surfaces exhibiting a significant subsurface O-coverage.</p>10aAdsorption10akinetics10aOxidation10aPalladium10asurface analysis1 aGopinath, Chinnakonda, S.1 aThirunavukkarasu, Kandasamy1 aNagarajan, Sankaranarayanan  uhttps://library.ncl.res.in/content/kinetic-evidence-influence-subsurface-oxygen-palladium-surfaces-towards-co-oxidation-high-0
