Hydrogen Uptake in Carbon-based Spiral-nanostructures

We perform a theoretical investigation to estimate the hydrogen storage capacity in carbon-based spiral-nanostructures (CSNSs). The chosen storage systems are both intrinsic and lithium-doped CSNSs. The results show that due to small interlay distance intrinsic CSNSs do not uptake hydrogen at ambient pressure and temperature. However, lithium-doped CSNSs can uptake significant amount of hydrogen, giving an uptake capacity of 3.3 wt%.
