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. ...

متن کاملNeutral and charged boron-doped fullerenes for CO2 adsorption
Recently, the capture and storage of CO2 have attracted research interest as a strategy to reduce the global emissions of greenhouse gases. It is crucial to find suitable materials to achieve an efficient CO2 capture. Here we report our study of CO2 adsorption on boron-doped C60 fullerene in the neutral state and in the 1e (-)-charged state. We use first principle density functional calculation...
متن کاملStructural and thermal properties of silicon-doped fullerenes
Extensive Molecular Dynamics simulations have been performed to investigate the structural and thermal properties of Si-doped fullerenes containing one and two silicon atoms. Both, a many-body potential and ab initio Density Functional Theory ~DFT! have been used to investigate the structural features of the heterofullerenes. The competition between the exohedral and the substitutional types of...
متن کاملNondissociative adsorption of H2 molecules in light-element-doped fullerenes.
First-principles density functional and quantum Monte Carlo calculations of light-element doped fullerenes reveal significantly enhanced molecular H2 binding for substitutional B and Be. A nonclassical three-center binding mechanism between the dopant and H2 is identified, which is maximized when the empty p(z) orbital of the dopant is highly localized. The calculated binding energies of 0.2-0....
