Graphene and graphene-based materials are valuable to be used as hydrogen storage because of chemical inertness and high strength. Therefore a thorough study of hydrogen adsorption on graphene is of great interest. Although such studies have already been made for flat structures, rippled graphene was not properly addressed. In the present work, first-principles calculations of absorption of hydrogen atom on graphene with small amplitude zig-zag ripples were conducted. It was found that varying the ripple amplitude the binding energy for hydrogen atom attached inside the ripple can be lowered by about 25%, while for the hydrogen atom attahced from outside the ripple can be increased by 80%, compare to the adsorption on flat graphene.

石墨烯和基于石墨烯的材料由于化学惰性和高强度而非常有价值，可以用作储氢剂。因此，对氢在石墨烯上的吸附的深入研究非常重要。尽管已经针对平面结构进行了此类研究，但波纹石墨烯并未得到适当解决。在本工作中，进行了具有小幅度曲折波纹的石墨烯上氢原子吸收的第一性原理计算。研究发现，与在平坦石墨烯上的吸附相比，改变波纹幅度可以使附着在波纹内部的氢原子的结合能降低约25％，而对于从波纹外部附着的氢原子的结合能可以提高80％。 。
