内容記述
Introduction of edge and functional groups give graphene radical-like electronic states (SOMO). Spin magnetism and chemical activity for graphene oxide synthesized by Brodie and Hummers methods (BGO and HGO) and activated carbon fibers (ACFs) which is an edge-iched nanographene assembly material was investigated by the magnetic susceptibility, ESR and GC-MS. A catalytic reaction from benzylamine to N-benzylidenebenzylamine was carried out by using ACFs and GO as catalyst to evaluate their chemical activities. HGO shows the highest yield in the catalytic reaction irrespective to moderate spin density. ACFs and BGO exhibits similar chemical activity although ACFs has the largest spin density. The presence of conduction electron is also important in the catalytic reaction. Key Words : graphene oxide, nanographene, magnetism, chemical activity
