Novel carbon materials modified with heteroatoms as metal-free catalyst and metal catalyst support
The discovery of novel carbon materials (carbon nanotubes, graphene) has extended the window for the application of carbon materials as catalyst and catalyst support. The electronic conductivity, ordered structure and absence of microporosity are some favourable properties compared to disordered conventional carbon materials. The ordered nature of these materials allows the precise functionalization with heteroatoms which have shown good perspectives as metal free catalyst. Herein, the more recent catalytic applications of heteroatom modified novel carbon materials both as catalyst and catalyst support are reviewed.
