The electrically conducting hydrophobic surface of carbon nanotube arrays can be used as cathode for hydrogen generation by electrolyzing water. This movie shows the hydrogen evolution from cathodic Carbon nanotubes and oxygen bubbles at anode during electrolysis of water. Carbon nanotubes demonstrated the possibility of reversible hydrogen absorption inside the CNTs foams. This unique highly hydrophobic/highly conductive hybrid response of the CNT forests has potential for being employed in highly efficient compact fuel cells.
