内容摘要

Chemical doping of the graphitic lattice with heteroatoms such as N, P and B can effectively tailor the physicochemical properties of sp2 nanocarbons. Importantly, the presence of heteroatoms would cause the rearrangement of the free electrons and endue the graphitic with chemical reactivity. Additionally, gas- or liquid-phase oxidation allows functionalizing edge or defective sites with oxygen atoms to produce various oxygen-containing groups such as carboxyl, phenolic hydroxyl and carbonyl. In recent years, many researches have demonstrated the superior performance of the doped and functional carbon nanotubes or graphene when they catalyze the conversion of hydrocarbon and biomass. This talk will first review the recent progresses of doping and functionalization methods in literature, and focus on several facile and economical routes from the industrial viewpoint. The catalytic performance and working mechanism of CNTs and graphene in typical reactions for biomass conversion and electrocatalytic oxygen reduction will be introduced.
