Molecular Dynamics Simulation of Hydrogen Adsorption on Silica

Abstract

Hydrogen is one of the future energy because it is enviromentally friendly. However, there still some problem in the storage method of hydrogen. In its development, there are many candidates that are still in research as a hydrogen storage medium. Also in several studies, it was found that Silicon based material is a promosing candidate. In this study we conduct the effect of various pressure to the adsorption of hydrogen on Silica with molecular dynamics simulation using Lennard-Jones potential. The simulations indicate that Silica has a good hydrogen storage capability where pressure and time affect the amount of hydrogen adsorbed.
