The adsorption of a hydrogen atom on the two types of boron sheets surface

Abstract

The possible connection between the atom of hydrogen and the surface of twodimensional boron sheets have been investigated. The calculations were carried out within the model of molecular cluster with the use of quantum chemical MNDO scheme. Two types of BS were studied: triangular BS (TBS) and α-sheet of boron atoms (αBS). The hydrogen atoms attacking BS have been simulated by a step-by-step approach for all atom locations. The surface patterns of potential energy for these processes were built. The analysis of curves showed that the active atom of hydrogen is adsorbed on the surface of BS. The adsorption distances (Rad) and the adsorption energy (Ead) were calculated. We have proved that αBS has a greater sorption capacity than hydrogen TBS.
