Synthesis and Evaluation on Performance of Hydrogen Storage of Multi-Walled Carbon Nanotubes Decorated with Platinum

By means of chemicol reduction, nanopartieles of platinum were deposited on the surface of multi- walled carbon nanotubes ( MWCNTs ). The perforrrumce of hydrogen storage of as-prepared MWCNTs deco-rated with platiman was investigated. The results indicate that : ( 1 ) Hydrogen uptake is more quick and intense for decorated MWCNTs than that for not decorated ones at 10.931MPa and room temperature. The saturation of hydrogen uptake of the former only lasts about 30min,while the lafter needs about 150 min; (2) The amount of hydrogen uptake of decorated MWCNTs /s about 1.13wt%, wh/ch is larger than that of not decorated ones( about 0.54wt% );(3) Hotcrter ,more than 37% hydrogen absorbed by decorated MWCNTs is chenisorbed.
