报告摘要

It is of great importance to construct active site with high intrinsic activity for a certain reaction. Followed by achieving high dense of such active sites into a catalyst, the overall activity can be significantly promoted. Defects on carbons can not only serve as active sites, especially by a series of modification for electronic and molecular structures, with high intrinsic activity, but also can provide a large number of sites for trapping various atomic metal species, achieving high density of active sites. In 2015, we firstly initiated the concept of defect mechanism for ORR, then expanded it to hydrogen evolution (HER) and oxygen evolution reactions (OER), gradually establishing the new research field of defect electrocatalysis in the following years. The defect can provide enormous advantages for trapping atomic metals such as Ni, Co, Fe as examples with different coordination, e.g. defective materials, to activate chemical reactions such as oxygen reduction, hydrogen and oxygen evolution reactions. The numbers of the active sites can be controlled by the precisely control of defect synthesis. This new strategy provides opportunities to develop catalysts with high activity and high stability. Accordingly, it should be a future research focus for next generation catalysts that the design of active site with high intrinsic activity and assembly of the active sites with precisely controllable numbers into a catalyst.
