摘要：

Nickel nanoparticles were deposited on multiwall carbon nanotubes (Ni-MWCNT) in a single step by electroless plating technique. The effect of bath composition on the resulting nanoparticles was examined by scanning and transmission electron microscopy. To improve nickel dispersion a surface treatment was made to raw MWCNT. Hydrogen storage measurements were determined at 77 K and atmospheric pressure and also at 303 K in the pressure range of 0.1 to 5 MPa. Results show that highly dispersed nickel nanoparticles were deposited on the external MWCNT wall using hydrazine as reducing agent. Surface modifications help to improve hydrogen storage. For Ni-MWCNT hydrogen storage was increased two times compared to raw MWCNT at 303 K and 5 MPa.
