報(bào)告摘要:
The development of high-performance and low-cost catalytic materials for the Oxygen Reduction Reaction (ORR) has been the key issue for the large-scale application of fuel cells. To meet this challenge, non-platinum catalysts have been systematically studied in our group. Recently, we have being devoting to designing of nitrogen-doped graphene (NG) and finding new properties of transitional base metals. We propose a space-confinement-induced strategy of selectively generating planar pyridine and pyrrolic NG with layer-structured montmorillonite (MMT) used as the quasi-closed flat nano-reactor.[1] We further compose a “shape fixing via salt recrystallization” method to efficiently synthesize nitrogen-doped carbon material with a large number of active sites exposed to the three-phase zones and construct a three dimensional network catalyst structure with a high density of ORR active sites.[2] In the aspect of investigating mechanism of hetero atoms-doped carbon in catalysis of ORR, we propose so-called triple-effect theory, i.e., charge, spin density and ligand effect, to well explain the enhanced catalysis of hetero atoms doped carbon. [3] In addition, we reveal a new structure-activity relationship between spinel crystalline structure and ORR activity toward the traditional FeCo base metals. [4]
