Two-dimensional conjugated N-rich covalent organic frameworks for superior sodium storage
文献摘要：
Sodium-ion batteries(SIBs)are considered as a promising next-generation energy storage system.To achieve the large-scale application of SIBs,it is crucial to develop cost-effective anode materials with high Na-ion storage capacity.Herein two-dimensional(2D)conjugated covalent organic frameworks(cCOFs)with N-rich phthalocyanine(Pc)units fused via benzene moieties(named MPc-2D-cCOFs)were explored as the SIBs anode materials.Electrochemical tests reveal their high reversible capacities of 538 and 342mAhg-1 at 50 and 1000 mA g,respectively,good rate performance,and excellent stability,comparable to the state-of-the-art anode materials of SIBs,indicating their outstanding Na-ion storage performance.Ex situ X-ray photoelectron and Fourier transform infrared spectroscopies together with theoretical calculations disclose the N atoms at the pore channels and conjugated pyrrole moieties of MPc-2D-cCOFs provide abundant Na-ion storage sites.This,in cooperation with the enhanced electrical conductivity owing to the 2D conjugated structure,contributes to the outstanding Na-ion storage capacity of MPc-2D-cCOFs.The present result is surely helpful for developing high-performance and cost-effective COFs as electroactive materials for SIBs.
