An electrochemical method is used to open multi‐walled carbon nanotubes at a room temperature. HRTEM analysis (see Figure, arrows indicate openings) and cyclic voltammetry were undertaken and showed that, owing to the oxidation reactions occurring preferably at the end regions of nanotubes, an enhanced amount of hydrogen is stored in the nanotubes, which, during the cathodic reduction, is reversibly recovered.
