Theoretically Predicted CO Adsorption and Activation on the Co-Doped hcp-Fe7C3 Catalyst

Theoretical insights into the adsorption behavior of CO molecules on the pure and Vn-doped BN nanotubes

Interaction of pure and Vn-doped (8, 0), (12, 0) and (16, 0) boron nitride nanotubes with CO molecules was studied using B3LYP/6-311++G(d) theoretical level. Substituting V instead of B atoms, increased the reactivity of nanotube. From the results, the complex stability depends on the direction and the number of the CO molecules interacted with the nanotube. In this work, the quantum...

CO Adsorption and Activation on Supported Cu Nanoclusters

Magnetic Properties of Fe Doped, Co Doped, and Fe+Co Co-Doped ZnO

The structural, electronic and magnetic properties of Zn0.95Co0.05O, Zn0.95Fe0.05O and Zn0.90Fe0.05Co0.05O nanoparticles prepared by a sol-gel method are presented and discussed. Xray diffraction and optical analysis indicated that high spin Co ions substitute for the Zn ions in tetrahedral sites. Fe Mössbauer spectroscopy showed the presence of isolated paramagnetic Fe ions in both Fe doped an...

CO Adsorption on Co(0001)-Supported Pt Overlayers

the growth of Pt deposits on Co(0001) was followed by STM and XPS. The chemical reactivity of the resulting surface was checked by CO adsorption. Pt grows as dendritic islands on the Co terraces whereas forming stripes at the Co step edges. Annealing the sample has no apparent effect on the STM pictures. However, XPS suggests that a limited dilution of Pt in Co takes place. The adsorption of CO...

Vibrational spectroscopic studies on CO adsorption, NO adsorption CO þ NO reaction on Pd model catalysts

CO adsorption, NO adsorption and CO þ NO reaction on various Pd model catalysts have been studied using vibrational spectroscopy from ultrahigh vacuum (UHV) up to elevated pressures (B1 bar) and the kinetics of the reaction compared with the conventional high surface area Pd/g-Al2O3 catalysts. The structure sensitivity of the CO þ NO reaction on different Pd surfaces is explained using Pd(111),...
