چکیده

plane-wave pseudopotential density functional theory (oft) periodic slab calculations were performed usingthe giteralized gradient approximation (gha) to investigate the adsorption of nitric oxide(no) on the (i ii)surface of cu. copper rface was stimulated using th p 'odic slab method consisting of five atomic layers.four different adsorption saes (atop. bridge, rcp hollow, and fcc hollow) were considered. resultsspecified that the suitable site for no adsorption in molecular foun is the hollow fcc site, and molecularadsorption is more stable than dissociative adsorpnon energetically.

Plane-wave pseudopotential density functional theory periodic slab calculations of CO adsorption on Cu2O(111) surface

Plane-wave pseudopotential Density Functional Theory (DFT) periodic slab calculations have been performed to investigate carbon monoxide adsorption on the (111) surface of Cu2O. Negligible relaxation of this surface was found (surface energy = 0.71 J m ), consistent with its non-polar nature. The on-top-Cu site of CO adsorption is favoured, with a binding energy of 1.50 eV. After adsorption, th...

Electronic Properties of Hydrogen Adsorption on the Silicon- Substituted C20 Fullerenes: A Density Functional Theory Calculations

The B3LYP/6-31++G** density functional calculations were used to obtain minimum geometries and interaction energies between the molecular hydrogen and nanostructures of fullerenes, C20 (cage), C20 (bowl), C19Si (bowl, penta), C19Si (bowl, hexa). The H2 molecule is set as adsorbed in the distance of 3Å at vertical position from surface above the pentagonal and hexagonal sites of nanostructures. ...

Adsorption Behaviors of Curcumin on N-doped TiO2 Anatase Nanoparticles: Density Functional Theory Calculations

The density functional theory (DFT) calculations were used to get information concerning the interaction of curcumin with pristine and N-doped TiO2 anatase nanoparticles. Three adsorption geometries of curcumin over the TiO2 anatase nanoparticles were studied in order to fully exploit the sensing properties of TiO2 nanoparticles. Curcumin molecule adsorbs on the fivefold coordinated titanium si...
