چکیده انگلیسی
Hydrogen storage property of Si-carbon nanotube composite was studied. It was found that the carbon nanotube coated Si particle was prepared by the decomposition of tetramethylsilane by using Ni catalyst. The obtained composite was consisted of the spherical Si particle with 300Â nm diameter and the surface of Si particle was coated with carbon nanotube with 10Â nm diameter. The obtained Si-carbon nanotube composite shows a fairly large hydrogen storage capacity of 2.5Â wt%. The amount of storage H2 increased with increasing the preparation temperature and the largest hydrogen storage amount could be achieved at 1273Â K for 6Â h. Fairly large hydrogen storage capacity could be sustained after 3 cycles of adsorption and desorption.
