摘要

Abstract

Hydrogen adsorption performance of a superactived carbon (Maxsorb) doped with Ni nanoparticles

prepared using plasma method

was studied.By comparing the material with sample prepared using traditional H2 reduction

the effect of plasma on structure and performance of adsorbing H2 of these samples was analyzed.The hydrogen storage capacity was significantly increased for plasma treatment samples.The H2 storage capacity for Ni-doped Maxsorb at 298 K and 10 MPa was 1.17%(mass)

and only 0.98%(mass) for H2 reduction sample and 0.68% (mass) for pure Maxsorb one.Doping of Ni made storage capacity of carbon increase via hydrogen spillover mechanism.The sample with plasma treatment had smaller Ni particles that were highly dispersed on carbon.Meanwhile

it was found that there was stronger anchoring and more intimate contacts between metal and carbon.The increase of adsorption heat for the sample with plasma treatment suggests that the bonding between hydrogen atoms and the surface of Ni/Maxsorb was stronger

which was in agreement with high-pressure hydrogen adsorption results.
