چکیده

Magnesium, nanotubes, graphitic nanofibers, and graphite represent interesting opportunities for efficient hydrogen storage applications and motivate first-principle investigations of the hydrogen energetics and dynamics that describe such potential technological usage. We present spin-polarized electron-density calculations of adsorption energies and diffusion barriers for both chemisorbed and physisorbed hydrogen atoms to provide a detailed description of the important hydrogen dynamics.

Molecular Dynamics Simulation of Collisions between Hydrogen and Graphite

Hydrogen adsorption by graphite is examined by classical molecular dynamics simulation using a modified Brenner REBO potential. Such interactions are typical in chemical sputtering experiments, and knowledge of the fundamental behavior of hydrogen and graphene in collisional conditions is essential for modeling the sputtering mechanism. The hydrogen adsorption rate is found to be dependent on t...

Molecular Dynamics Simulation of the Hydrogen Isotope Sputtering of Graphite

We used a molecular dynamics simulation with the modified Brenner reactive empirical bond order potential to investigate the erosion of a graphite surface due to the incidence of hydrogen, deuterium, and tritium atoms. Incident particles cause pressure on the graphite surface, and the chemical bond between graphene layers then generates heat to erode the graphite surface. We evaluated the speed...

Molecular Dynamics Simulation of Chemical Sputtering of Hydrogen Atom on Layer Structured Graphite

Chemical sputtering of hydrogen atom on graphite was simulated using molecular dynamics. Especially, the layer structure of the graphite was maintained by interlayer intermolecular interaction. Three kinds of graphite surfaces, flat (0 0 0 1) surface, armchair (1 1 2 0) surface and zigzag (1 0 1 0) surface, are dealt with as targets of hydrogen atom bombardment. In the case of the flat surface,...

Molecular Dynamics Simulation of Plasma Surface Interaction

New interlayer intermolecular potential model was proposed and it represented “ABAB” staking of graphite. Hydrogen atom sputtering on graphite surface was investigated usingmolecular dynamics simulation. In the initial short time period, maintaining the flat structure of graphenes, hydrogen atoms brought about the difference interaction process in each incident energy. The first graphene often ...

Photocatalytic hydrogen evolution on dye-sensitized mesoporous carbon nitride photocatalyst with magnesium phthalocyanine.

Spectral sensitization of a mesoporous graphite carbon nitride (mpg-C(3)N(4)) photocatalyst was investigated by depositing magnesium phthalocyanine (MgPc) to expand the absorption to wavelengths longer than those of the principal mpg-C(3)N(4). The obtained sample, MgPc/Pt/mpg-C(3)N(4) (Pt as a cocatalyst) showed stable photocatalytic evolution of hydrogen from aqueous solution in the presence o...
