Abstract
 The curvature dependence of the physisorptions of H2 on graphene surface and their barrier to the chemisorptions has been studied. The graphene with steeper curvature can adsorb H2 stronger due to the more sp3 character of the carbon. However, for the negative curvature, the binding strength of the physisorption and the barrier to the chemisorptions are determined by steric repulsion as well as the sp3 character.

How to access to the WOL for The Bulletin of the Korean Chemical Society ?

The Bulletin of the Korean Chemical Society will be co-published with Wiley-VCH from 2015 towards. The online version of the Journal will thus be available on Wiley Online Library, Wiley(-VCH)'s global online platform.

KCS members can get a free online access to the Bulletin of the Korean Chemical Society in WOL.
