A review on recent advances in hollow spheres for hydrogen storage
Not only the hollow nanosphere structure decreases the operative temperatures, but also the rate of adsorption enhances dramatically. The Li 2 NH hollow nanospheres sample uptake 6.0 wt% hydrogen at 200 °C in 60 s while Li 2 NH micrometer powders uptake 1.6 wt% hydrogen in 1 h at a similar temperature.
