Abstract Graphene hydrogenation gives an opportunity to introduce a band gap into the graphene electronic structure. Complete hydrogenation may lead to the graphane, a fully hydrogenated counterpart of graphene. However, pure graphane has not been successfully prepared to this day. Here, we show that hydrogenation of single‐walled carbon nanotubes by means of Birch reduction leads to graphene‐based carbon nanostripes with uniform dimensions. Such a material exhibits interesting electrocatalytic and magnetic properties as well huge potential for hydrogen storage since the weight concentration of hydrogen is 8.78 wt.% corresponding to the composition of C 1 H 1.22 O 0.05 and thus exceeding the theoretical concentration in pure graphane (7.74 wt.%). The obtained concentration of hydrogen is the highest value ever reported for any graphene‐based material and significantly exceeds the ultimate goal of the U.S. Department of Energy for a hydrogen storage material of 7.5 wt.%.
