SYNTHESIS AND CHARACTERIZATION OF HIGHLY N-DOPED POROUS CARBON MATERIALS AND THEIR APPLICATOINS AS ELECTROCATALYSTS IN FUEL CELLS

摘要

Nitrogen incorporated mesostructured materials have received increasing attentions in several scientific disciplines during the past decade. It has been shown that the presence of nitrogen in carbon materials not only promotes the dispersion of metal catalyst but also enhances the electrocatalytic properties of the supported catalysts [1,2]. In general, N-containing carbon nanostructured materials can be prepared either in-situ doping or post-doping [3]. The former involves direct N-doping during fabrication of the porous carbon, whereas the latter may be achieved by post-treatment of the pre-synthesized carbons with an N-containing precursor.
