| Abstract: | Carbon nano-tubes (CNT) have attracted the attention of the whole world since they were claimed to be the exclusive candidate carrier of hydrogen for the hydrogen vehicle.However,the reports on hydrogen storage materials are quite controversial.In this review,the recent progress on the morphology,microstructure,synthesis,theoretical calculation,hydrogen storage property and electrochemical hydrogen storage of CNT was investigated.The results obtained from a large number of experiments and simulation studies show that CNT has an ideal microstructure suitable for hydrogen storage,and the properties of which is closely associated with the preparation of CNT,testing methods and calculation.Such factors as a large surface area,a big diameter,the surface activation and adulteration are effective elements to improve the hydrogen storage property of CNT. Oriented multi-walled Carbon nano-tubes (MWNTS) have better electrochemical properties than the normal MWNTS. |
