英文摘要Metal single-atom catalysts (SACs) are extensively investigated to accelerate the sulfur redox kinetics in room-temperature sodium & horbar;sulfur (Na & horbar;S) batteries. Nevertheless, the influence of the structure symmetry of SACs center on the electrocatalytic mechanism and the precise pathway in which single-atom active sites facilitate sodium polysulfides (Na2Sn) conversion remain unknown. To enable controlled construction of highly active single-atom configuration, herein, Zn SACs with an asymmetrical Zn & horbar;N3O configuration are designed for sodium polysulfides conversion. Both theoretical and experimental explorations reveal that the Zn & horbar;N3O single-atom center displays higher electrocatalytic activity for polysulfides conversion than the Zn & horbar;N-4 single-atom center. The N/O co-coordination induces the localized charge at Zn single-atom center, which strengthens the d-p hybridization with Na2Sn and stretches Na & horbar;S bond length of Na2Sn, thus accelerating the sulfur redox reaction kinetics. Consequently, the as-assembled Na & horbar;S batteries achieve a high capacity of 1016 mAh g(-1) at 1.0 C with a capacity decay of 0.0186% per cycle over 1000 cycles. This work uncovers the subtle relationship between the electrocatalytic activity of species conversion and the local coordination environment of SACs, and offers a guidance for the design of efficient asymmetrical SACs for different catalysis applications.
