Herein, a metal\u2013organic framework (MOF)\u2010on\u2010MOF self\u2010templated strategy is used to fabricate okra\u2010like bimetal sulfide (Fe<jats:sub>7<\/jats:sub>S<jats:sub>8<\/jats:sub>\/C@ZnS\/N\u2010C@C) with core\u2013double\u2010shelled structure, in which Fe<jats:sub>7<\/jats:sub>S<jats:sub>8<\/jats:sub>\/C is distributed in the cores, and ZnS is embedded in one of the layers. The MOF\u2010on\u2010MOF precursor with an MIL\u201053 core, a ZIF\u20108 shell, and a resorcinol\u2013formaldehyde (RF) layer (MIL\u201053@ZIF\u20108@RF) is prepared through a layer\u2010by\u2010layer assembly method. After calcination with sulfur powder, the resultant structure has a hierarchical carbon matrix, abundant internal interface, and tiered active material distribution. It provides fast sodium\u2010ion reaction kinetics, a superior pseudocapacitance contribution, good resistance of volume changes, and stepwise sodiation\/desodiation reaction mechanism. As an anode material for sodium\u2010ion batteries, the electrochemical performance of Fe<jats:sub>7<\/jats:sub>S<jats:sub>8<\/jats:sub>\/C@ZnS\/N\u2010C@C is superior to that of Fe<jats:sub>7<\/jats:sub>S<jats:sub>8<\/jats:sub>\/C@ZnS\/N\u2010C, Fe<jats:sub>7<\/jats:sub>S<jats:sub>8<\/jats:sub>\/C, or ZnS\/N\u2010C. It delivers a high and stable capacity of 364.7 mAh g<jats:sup>\u22121<\/jats:sup> at current density of 5.0 A g<jats:sup>\u22121<\/jats:sup> with 10\u00a0000 cycles, and registers only 0.00135% capacity decay per cycle. This MOF\u2010on\u2010MOF self\u2010templated strategy may provide a method to construct core\u2013multishelled structures with controlled component distributions for the energy conversion and storage.<\/jats:p>","DOI":"10.1002\/smll.201907641","type":"journal-article","created":{"date-parts":[[2020,7,31]],"date-time":"2020-07-31T05:50:24Z","timestamp":1596174624000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":127,"title":["Okra\u2010Like Fe<sub>7<\/sub>S<sub>8<\/sub>\/C@ZnS\/N\u2010C@C with Core\u2013Double\u2010Shelled Structures as Robust and High\u2010Rate Sodium Anode"],"prefix":"10.1002","volume":"16","author":[{"given":"Dongwei","family":"Cao","sequence":"first","affiliation":[{"name":"School of Materials Science and Engineering College of Science China University of Petroleum (East China)  Qingdao Shandong 266580 P.
