D-22: Hydrogen Storage Properties of Graphitic Carbon Nitride Nanotubes Synthesized by Mix-grind Technique: Barton Arkhurst¹; Ruiran Guo¹; Ghazaleh Bahman Rokh¹; Sammy Chan¹; ¹University of New South Wales
    Hydrogen has been touted as the fuel to potentially replace fossils, however, the bottleneck towards its acceptance is its storage and transportation in a manner considered practical and safe. For mobile applications, hydrogen has the potential to be used in fuel cell powered cars as a clean fuel, however, its realization rests on its efficient mode of storage. Presently, the technique of storing hydrogen in pressurized tanks at 700 bar has safety concerns. In this work, we report a mix-grind technique of synthesizing graphitic carbon nitride (g-C3N4) nanotubes as hydrogen storage materials. The morphology, crystal structure, surface and hydrogen storage properties of the samples were analyzed. Results showed a high specific surface area of about 114.21 m2/g and hydrogen storage capacity of 0.67 wt.% at 37 bar was achieved at room temperature.
