摘要: Abstract In this paper, we have addressed the structural stability and hydrogen storage capability of single side double Na-decorated γ-Graphyne, Graphyne-like Boron Nitride CCBN-yne, using three methods density functional theory approximation: PBEsol, vdW-DF2-B86R vdW-DF2. We also investigated electronic properties these structures, decorated by Na atoms adsorbing hydrogen, such as states band structure. Our results showed that can be adsorbed up to molecules per atom. found optimal geometries on adsorption candidates. Direct band-gap at “M” point changes after decoration in mentioned structures. Finally, explored metallic structures for which used industry fuel cells.
