AbstractThe hydrogen adsorption capacity of various carbon nanostructures including single-wall carbon nanotubes, graphitic nanofibers, activated carbon, and graphite has been measured as a function of pressure and temperature. Our results show that at room temperature and a pressure of 80 bar the hydrogen storage capacity is less than 1 wt.% for all samples. Upon cooling, the capacity of hydrogen adsorption increases with decreasing temperature and the highest value was observed to be 2.9 wt. % at 50 bar and 77 K. The correlation between hydrogen storage capacity and specific surface area is discussed.

Hydrogen Migration

The hydrogen adsorption on platinum (Pt)-decorated carbon nanocenes (CNCs) are investigated by DFT calculations. The Pt is an active site for hydrogen adsorption while curvature of CNC enhances hydrogen uptake via hydrogen migration/diffusion on the C–C surface.

AbstractActivated carbons and carbon nanotube were synthesized with chemical and microwave processes of olive leaf in media with and without ultrasonic waves, and chemical vapor deposition method, respectively. The samples were characterized by x-ray diffraction, calorimetry, Brunauer, Emmett and Teller method, scanning electron microscopy/energy-dispersive X-ray, and zetasizer nano S90 instruments. The activated carbon synthesized in the ultrasonic bath had a higher surface area. The hydrogen adsorption capacity of carbon structures including activated carbons and carbon nanotube was measured as a function of pressure at 77 K. The hydrogen storage capacity of the carbon nanotube is 300% and 265% higher than the hydrogen storage capacity of activated carbons synthesized in medium without and with ultrasonic waves, respectively. Results showed the correlation between hydrogen storage capacity and specific surface area. The highest H2 storage value was obtained with carbon nanotube at 77 K. As a result, activated carbon and carbon nanotube can be used in hydrogen storage and therefore, the olive leaf can be converted into a high added value product in the energy field.
