英文摘要	Development of efficient catalysts with low cost for the oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) has been a long-term pursuit because of their vital role in renewable-energy technologies including fuel cells and water splitting. Herein, based on polymerizable ionic liquids (PILs) functionalized with nitrate groups as pore former and precursor of C and N, a facile one-pot thermal treatment method was developed to construct a hybrid electrocatalyst consisting of earth-abundant materials, which was made of Co-based nanoparticles (NPs) grown on 2D N-doped and macroporous carbon nanosheets (pCNs) of approximately 20-50nm thickness, that is, Co-N-pCNs. The obtained Co-N-pCNs catalyst manifests enhanced catalytic performance for both ORR and OER, even compared with the best-known commercial catalysts, such as Pt/C and IrO2. The enhanced catalytic activity arises from the 2D nanosheets and porous structures, well-dispersed Co-based NPs on the carbon sheets, the introduction of electron-rich nitrogen, and the stability by the carbon protection of Co-based NPs between the interlayers of nanosheets. Our present work supplies a novel opportunity for exploring 2D non-precious-metal catalysts for ORR and OER.; National Natural Science Foundation of China [21303119, 21576211, 21504063, 21501131]; Tianjin Research Program of Application Foundation and Advanced Technology [15JCQNJC05300, 13JCYBJC41600]; Program for Chang- jiang Scholars and Innovative Research Team in University of Ministry of Education of China [IRT13084]; Science and Technology Plans of Tianjin [15PTSYJC00230, 15PTSYJC00240]; SCI(E); ARTICLE; 9,SI; 1601-1609; 9
